We camped at Tall Pines Harbor Campground in Temperanceville, Va Easter weekend and paid this dealer a visit. They had a nice stock of golf carts but am not too sure about their parts supply. I think Pocomoke City is about an 1.5 hours north of you though.
Enjoy Cherrystone! We camped there last year with some friends and had a blast!
