I'm going to be staying in downtown San Antonio 8/23 - 8/27. I checked into a couple of bike shops, but it costs as much to rent a bike as it does to rent a car.

I don't need an expensive road bike. I just want a basic bike to tool around with for a few days. Anyone here have a beater they are willing to lend? A hybrid/flat-bar/commuting style bike would be fine. I'll bring my own lock, lights, and helmet.
