I think Mt. PLeasant has a ride group. Mt. Pleasant is very close to there. I think there is a shop there and you can contact them as to rides and info. on rides. Unfortunately, I can't remember the LBS name.
While there might I suggest you dine at Stickey Fingers either in Mt. Pleasant (the original) or on Meeting St. in downtown Charleston on the main drag! Damn good ribs my friend.
