This is a great show in a super location. It has my highest recommendation. I've attended 3 times over the years with:
2001 Hyundai (Our 1975 IH Scout broke down the night before departing)
1975 IH Scout (This trip convinced me that I needed to install an air conditioner)
1986 Ford F150 (2 years ago - The first major trip after the 4bt installation - see link below)
Our Colorado kid has moved, so, we probably will not get back again.
