I dont know if Brian Willis has any specific details about the NFGT or is speaking in generalities, but it's probably worth a visit if you are local. In any case, it might be a good excuse to have some of the local GTs get together. AMP is at the base of the mountains and we could take a cruise on some of the back roads. Let me know if anyone is interested.
