Our system loses money, which is covered by the city. It's a good investment because every time someone rides a bike instead of driving, it means less wear and tear on the roads, cleaner air, healthier citizens, less risk of someone being maimed or killed by a car, etc. There was a lot of vandalism during the first year or so after the program was started. Extreme right-wing groups, VC fanatics, cab drivers and drunkards were thought to be responsible for most of it. The vandalism now seems to have disappeared. Not sure why.
