VanHoy Farms is a campground near Harmony NC, just off I-77.  There were no tent campers while we were there (though it is available), but many RV sites, both seasonal and nightly available.  

VanHoy Farms runs parallel to the highway, but with the large trees and brush, highway noise was not an issue (from the second loop).  This was a dog-friendly campground for sure - several pups were running around without leashes on, but all with owners.  

Great views of rolling green hills and the pool were added benefits!  Several families were using the pool while we were there.  We would like to come back for one of their music festivals - they have several scheduled.
