Back on the bike today.

I feel about 100% better than I did yesterday. I think in the future when I'm on vacation and not hiking or something, I need to jump on the bike for 15 or 20 miles at least every 3 or 4 days. Without it I feel just a little worse every day, and by the time a week passes, I don't have a lot of energy left.

Procedural problem...

If you don't already have something to cut with, you're kind of S.O.L.
