Ah...I forgot about the Prineville ride. You are right, of course. I'm sure the BH must be the oldest in the MT region, though. Thanks for the history. Cindy
I think Prineville in Oregon has it beat. I don't recall off the top of my head the exact starting year, but it has been put on continuously since sometime in the 1960s... (And of course, that predates AERC, as does Bighorn...)
