Jack,
Welcome to central North Carolina. There is a bit of 3 rail activity in the area as well as a fair amount of 2 rail O. Train show May 1-2 at fairgrounds in Raleigh. It is sponsored by the Neuse River Valley Model Railroad Club. See our website at nrvclub.net.
Come visit at Nicks Trains at 5201 Oak Park Rd , Raleigh. We have a large inventory of new and used 3rail as well as HO, N and Z. Introduce yourself when you come by. I work there 4 days a week.
