There's the Indian Creek Greenway. Many people from Hampton Cove and other "upper class" areas have gotten their townies from MC. I really don't know where they ride, as I rarely use the greenway. The old store was SUPER crowded. You should check out the new store.

I liked the prices and MTB selection at Bikes Etc, but they had a few short comings. They only had one pair of aero bars [and they were charging too much] and I they have a couple of mechanics that are neglecting a bit of maintanence. I actually had to work on my friend's brand new Trek hybrid that he bought there. It wasn't anything major, just adjusting the brakes and shifting a bit. Other than that, it's a good place.

MC was only carrying a few MTBs, but they've stepped it up a bit. There's still not as much as Bikes etc. They're carrying Scott, Fuji, and Titus last I saw.
