I bit the bullet and rode to campus tonight (I'd been putting it off because I was scared of traffic and scared of locking up my bike.) Traffic was neglible; I walked through the two big intersections I had to cross. The ride took 20 minutes (after I got underway, I realized that Jeff was right and my tires needed air, so that'll probably be shorter tomorrow after we fill my tires) (also, it would have been a couple minutes shorter, but I forgot which side of the parking lot the bike racks were on and rode around a block I didn't need to) and locking it up was painless and took 2. This is a much better alternative to the 35 minute walk. I'm pleased, and happy.
I owe people comments. Tomorrow. You're all very sweet. :) I'm going to go face plant into my pillow, though.
