I've searched Woodalls, North Carolina state parks and South Carolina state parks for camping within reasonable distance of Gastonia. There are a number of KOA's and other private campgrounds but I'm leaning toward Kings Mountain State Park near Blacksburg, SC. Kings Mountain is about 25 miles from Gastonia.
Details for the state park can be found at
Camping - Kings Mountain State Park - South Carolina Parks and you can also reserve sites through
Campgrounds and Camping Reservations - ReserveAmerica
Let me know if there are other options.
I've contacted the booking agent for Ansty and the Troubs to see if there could be a Livin' in Aluminum party in the works. I'll keep you posted.
