Last time I attended, they drilled and placed four corner posts and you had to try to stay within those imaginary boundries. Usually, quite a bit of space, but throw a thousand, give or take, people out there and you may need to get friendly...
On a side note. The last time I did go, the adult liquids flowed pretty freely and I had to teach my cousin from Barnesville how to drive a stick shift on the ice so she could take me home.
A friend of mine has a trophy wife...I guess it wasn't first place.
