Moxfyre, that's a great idea about the caulk. I was worried about thieves with Allen wrenches.
I'm going to be tying my bicycle up in front of a busy library for around six hours a day, in the daytime. Can't shift it around every hour when it is on a different campus! I'm going to use skewers on the front wheel (I have already had the quick release saddle bolt replaced), a "Club" lock through the rear wheel attached to the bike rack, and a New Yorker lock through the frame and front wheel.
Hopefully that will do the trick.
