"On In! (defined)"

Definition: The On In is the end of the trail. The words "On In" are usually written (in flour or chalk) to show that you've made it to the end. "On In" is shouted when you reach the On In to let stragglers know where to go and let the people on trail behind you know they are close to the end. Depending on the hash, the On In may include snacks or real food, but it should definitely have beer and a circle.
