After 30 years of living in the Raleigh area, 6 months ago I moved to Solomons, Md. ( I still need to update my VAF profile). Raleigh Executive Jetport in Sanford (KTTA) has 15 or so active RV's based there. Tailwheel Adventures is an RV / Experimental completion center run by Terry Garner and is in a large hangar at the south end of the field.
Cox Field is in Apex and is home to EAA Chapter 1114. 100 plus active members and a number of them are also based at KTTA. Lots of builders here.
