The GoodGuys Colorado show is June 8, 9, 10 this year. There are usually 2000-3000 cars there, I have been told. We get cars from pretty far away, since we're fairly centrally located. There are some cars from Utah every year.....Kindigit Design.
I missed it last year, because I had to go brand cattle in Casper, WY. for the rancher who lets me hunt on his property. Lots of work, but it's fun.
