Urban DH is so gnarly. It would be cool if there where more of them in the states.
It would be. Only problem is closing off that much real estate in a city. I volunteer in my old home town every year for a local road bike race. All we close off is a 1 mile loop downtown for maybe 6 hours. The race brings a couple thousand tourists in, ready to spend money, and the local businesses COMPLAIN! Really?
