Thanks everyone for the great advice and wisdom. It's been a month since I first posted this and I've been up to my dainty eyebrows with work, so I haven't had a chance to look for a bike, any bike. I might just go to WalMart or something and get a tricycle. If it doesn't work out, I'll put it on Craigslist and keep looking for something else.

Who has the right of way on regular city streets: the car or the bicycle? I have found myself behind a bike many times, but because the left lane is full of cars, I had no choice but to plod along at 5 mph all the while staring at the bicyclist's butt and wondering when my butt is going to look that good!
