I surprised something...

on the way in to work, and it surprised me back.
Along a lonely back gravel road, something that sounded like a hawk or screech owl made a pretty loud, surprised sounding "Ska-reeek!" in a tree over my head. I think I woke it up. Well, it certainly woke me up too.
I'd just cleaned and lubed my drivetrain yesterday, and the studded tires don't make much noise on the gravel, so it was nice and quiet, so the bird got maximum scare out of its noise.
