A few years ago, I attended a show in Green Cove Springs, FL. in a horse arena at the fairgrounds. It seemed strange, at least to me, that there no cars being crushed, just jumping dirt hills. Wasn't a bad show for what it was. I'm guessing cars weren't used in order to avoid pieces of metal being mashed into the ground so they wouldn't later work back to the top and possibly injure a horse or other livestock. Just asking if this is common at smaller venues and other non MJ events?
