Our fair used to have calf scrambles, and though out the years it had changed, then finally it was stopped due to liability.
Years ago: The county cattleman got calves about 500 pound heifer calves from one farm. These calves were weaned but nothing else. Absolutely not gentle or halter broke. Then each kid got a rope halter. The calves were released into the show ring, and the goal was to catch a calf, halter it, then drag it to the "finish line". If you accomplished that, you kept the calf, then it was REQUIRED to bring that heifer back the following year as a bred heifer. If it was not, it was returned to the cattlemans.
After many years, and a few injuries, the calves got smaller, and then you just had to tie them to the closest post along ringside.
Then the calves got smaller yet, and after caught, the person drew a number. That number corresponded with a tag number to a larger heifer that was to be picked up at a later date (usually Nov-Dec)
I am not sure if the kids got to be too big of weanies, parents got sue happy, or the cattleman got tired, but the combination killed a jammed packed crowd during the scrambles (they also had a greased pig and lamb scramble), and a great program to get kids started. The kids who participated always got a critter (sometimes after a bit of time, help was granted) and every kid walked around with a sense of pride, especially when showing the bruises, cuts and grime they EARNED.
What wonderful memories!
