There are a couple in the Charleston Area. Not sure of what is up near Myrtle Beach but with Gulches Off Road Vehicle Park out towards Greenville, there has to be a few around =)
Im from Goose Creek stationed at the naval base. I'm about 2 hours south of myrtle beach but ive seen a few jeep clubs around here but never caught / remembered the names. Gulches looks great
i live in mt pleasant and would like to get into something like this too. found this on the web but not familiar with this club: http://www.lowcountryjeepclub.com/
