It's not the 16ish blocks there that I have a problem with... it's the 16 blocks after eating, drinking, waiting around until the last minute to go home, and then realizing I don't have a car there and have to walk 16 block back just to get it, and then go home that got me.
So... we rented bikes.
I've been wanting to buy a bike for a while now, and this just confirmed that I need to have one. We rented the obnoxiously bright city bikes. I had so much fun on them, and would do it again in a heartbeat.
