We have at least 6 inches of really wet, heavy snow on the ground after last night. I put the studs on the front in anticipation of SOME snow, but I put the rear on too before setting out this morning. I thought about putting a Nokian on the back, but since I took off the spoke reflectors, I decided to stick with a tire with reflective sidewalls.

Marathons off, Marathon Winters on, odometer 17158

The ride was actually pretty fun. It was very pretty in the first 3 miles through the woods, and the control wasn't bad, just a little wobbly 2 or 3 times. The worst part was that the car's tire track I was mostly riding through didn't avoid the washboard and potholes like I would have.

I wish I had taken a few pictures on the road, it was really very lovely, but here's one from the garage at home.

We got some wet snow last night, just enough to cover, and then it dropped from ~35*F to ~25*F. So I put a studded tire back on the front. Turns out to have been unnecessary, as I thought it would be, but it's not a big deal to swap tires and I don't need a spill.

Also, I patched the tube that went flat last week. This was my first time using the Harbor Freight patch kit. It's a heck of a deal and works fine. $2.49 (I actually paid $1.99) and contains twenty 1" patches (good for bike tires) and several smaller patches, TWO tubes of glue (good since they dry out after being opened for a year or so).

I actually used office supply rubber cement so I can save the unopened tubes for use on the road.

I put the patched tube back on the rear so I have the brand new tube as a spare. It now has 4 patches on it.

It's finally cold enough to feel like actual winter. I hate the middling stuff where it's close to freezing. The snow is squeaky underfoot like it should be. Yay! (-8°F this morning)

Maybe I spent too much time in the UP.

BTW I drove to work today - my legs took a beating on Riker road yesterday and would like a rest before tae kwon do tonight.

Record low

On the ride in this morning it was -4*F. Not nearly the coldest I've ridden in, just the coldest this year so far. Just keeping track.

Too warm

Normally I look at the thermometer when deciding what to wear on the ride to work. It was 39*F this morning. But I stuck my head out the door. It was damp and had been raining. Part of me said "Crud, it's cold out there. Put on that jacket, too." Then part of me says "No, you don't need all that crap, you'll just overheat." But the part that just crawled out of a warm bed didn't believe it and wanted to bundle up.

Net result; when this happens you can see me cruising into Dexter at 6AM with my jacket front and all the vents completely unzipped, if I haven't already had to stop and remove a layer.

What I need to do is just look at the thermometer and pick clothing and just go with it. Eliminate the visceral reaction to the cold. By Dec I have figured it out again and dress appropriately. But what I wore today for 39* would have been OK at 25*F or a bit lower. I've never really had a problem while cycling with being cold, even at -10*F. You can always just make more heat. But being too warm is uncomfortable and can lead to trouble if you sweat too much and it's really cold. I tend to just unzip and keep going when I really should stop and take off a layer.

Frost!

Rode through some fog on the way to work this morning, then a couple of miles later noticed some sparkly stuff on the grass. Looked at my computer and it said 31*F, so I guess that was frost! Admittedly it was only about a 200 foot patch, and the comp read 33*F 30 seconds later, but it was there.

Darn, it got cold fast. Mother nature doesn't usually pay that much heed to this "first day of fall" stuff.

Riding all winter (at least occasionally) pays off. I had my first ride of the year with the winter equipment off (studded tires, most of my winter clothes) and in not unusual conditions (the usual slight headwind, 60*F temp), my ride time went from the winter norm of 45-50 minutes to 37 minutes, which is a tad more than 1 minute faster than my fastest time last year.

Back here I described a nighttime light effect that I saw on the way to work, and theorized about the cause.

Today I found verification in Astronomy, Feb '99 Pg 74, "The Sky Show" column. Quoting from the article:

It's due to the combination of streetlights and a frigid air mass full of flat-based ice crystals.

Light from unshielded sources radiates upward and hits the bottom of reflective ice crystals in the atmosphere. The light then reflects back down toward your eye. From your point of view, the light appears to come from behind the crystal as part of a column above the light source. Reflections from thousands of crystals with slightly different orientations combine to make the whole pillar--even when you can't see the source. Temperatures of at least 0*F are needed to see this effect. This is one reason why such events are rare in the more temperate coastal regions.

Wednesday was my first day of riding in the slush. Tuesday night I put the studded tires on (at 2150 miles on the odometer).

Last Friday I put on full fenders and a front mudflap. This helps IMMENSELY. With just the "mud guard" on the front and a solid rack on the back, I'd pretty much written off riding in sloppy weather, but with the full fenders it's not a problem.

The "wintery mix" was coming down pretty well, very wet, by the time I got home. The only real discomfort at all was that it was basically raining ice pellets, and they hurt my face when I was riding into the wind. Also I was wearing half-finger gloves and my knuckles (but not my fingers) got cold. But I didn't really get wet until the last mile, where I was riding on a fairly slushy road, and the cars passing me were throwing up big sheets of slush which covered my legs. Still, it wasn't really a problem, it just sheeted off the windbreaker pants. My sneakers got wet, but when I got home the neoprene shoe covers I ordered were waiting, so that shouldn't be a problem in the future.

All in all, the winter riding is NOT a problem. You generate a surprising amount of heat, so you don't get cold, in fact my biggest problem is figuring out exactly how much clothing to wear; a couple of times already I've had to slow down a bit because I was overheating. I particularly tend to wear one too many layers on my legs. It's tough to step out into the dark morning and get on a bike when it feels like your legs are freezing, trusting that you'll be warm enough in 15 minutes.

Riding with the studded tires is interesting. A little more rolling resistance (not much), a lot more noisy. Riding through slush takes considerably more effort. My time for the trip was up from about 38 to 44 minutes, and my legs are letting me know about it today. So come spring I should be in pretty good shape! I'm going to get some fairly narrow tires for next year. The studded tires I have on now are actually more narrow than the hybrid tires I've been riding with.

I moved my Nashbar LED blinkie up to the back of my helmet (love those plastic quickties), and put a new one by Bell (same thing, different case) on the seatpost. I switched back to my 2.3 AH battery one day last week when I realized that I'd forgotten to charge my big battery overnight. For now I'm going to leave the 2.3 on, as I've found that riding with just the 3 LED white light on my helmet is NOT a problem on the paved roads. I flip on the halogen for the gravel (for pothole avoidance) and when there's an oncoming car. All told I have the halogen on for probably 20 minutes of the 40 minute trip. The 3 LED has been running on the same 3 AAA cells for 3 months now. Sure wish LED headlights were practical, but thus far they're pretty expensive and have a limited lifespan.

Eventually I think I'm going to get a new battery, a NiMH pack probably, that can handle 30 to 40 watts of light and give me 2 hours of runtime, then put on a 2nd light, probably a 10W flood. I'm thinking that I can run with the 10W most of the time, and use the 20W (or maybe both) when I get into busier areas. Dual lights seem pretty common, and it protects against having a bulb burn out leave you either running blind or changing a bulb in the dark in the freezing cold.

Nokians on (new)

Rolled over 2000 miles on the bike this past Friday. Woohoo! Time to put on the studded tires and shoot for 3000 for the 12 months since I started.

The weather reports are certainly based around "in town" when it starts getting cold. Last night they were saying lows in the 30's to high 20's. It was 17.2*F when I got up this morning.

Unfortunately I couldn't ride as I had committed to driving the minivan to run a bunch of errands and take the telescope to work for the Jupiter occultation this morning.

Of course the occultation was totally clouded out. A few sucker holes 10 minutes early through which we could see the moon, then a solid H20 blanket when it counted. It's currently 10 minutes to the exit event, and it's looking the same. Bleh.

Oh well, can't complain really, we had clear skies for the last 3 major events, which in itself is a miracle in Michigan.
