So I finally went out and settled on a Giant Escape 3. I hadn't ridden it more than 5 minutes before this morning when I rode it to work. I did learn a few things:

1. 17 miles is a looong way for me. I may just end up taking the train home depending on how I feel.
2. Riding at 5 in tha a.m. with no lights is really, really dark. Will definitely have to pick some up before I do this again.
3. My sitting parts are more sore than they've ever been. Is there a way to make this better? I tried sitting farther back on the seat, don't know if that helped or not.
4. Chasing down a nice 4 point mule deer on a bicycle is fun. I was hot on his heels until I remembered the antelope vs. cyclist video and dropped back.

Unfortunately due to scheduling between my wife and I, Tuesdays are the only days that I will be able to commute for now. I'll have to make time to ride other times in the week.

All in all it was a very enjoyable experience. Going to have to add lights, fenders, and maybe a rack and bags so as not to have to wear my backpack the whole time.
