I participate in one in TN every year. It's a good time. It's like $20 a rig to get in. They set up six challenge courses with the intent that most rig's will make them. The sixth course is a bonus course. Everyone draws numbers at the beginning to figure out which course they will start on so it splits everyone up a little. There is a judge at each course that passes out a card when each rig completes it. The cards are marked when they are passed out with the rig # so that people can't trade cards around. At the end of the run, best hand win's! Their run is a fundraiser, so they keep something like half the pot for the charity, the rest to the winner or something like that.
