Jason Burkett has a map of the cultivars in the planting and is the person to contact if you want to visit. Prilop and Carter are not at this location, they are in the south Alabama location.
Prilop has several weaknesses which is why I did not include it in the list of varieties to propagate above. It is getting scab pretty bad in some locations which means that scab has adapted to it as more acres are planted. It is a small nut though with good quality. I tried to graft Prilop 2 years ago but did not get any takes.
Tobacco Barn is probably worth investigating as a yard tree.
Here is a list of the trees at E.V. Smith excluding USDA numbered trees. Some of these cannot be provided as scionwood!
