Based on Kevins' report it sounds like the lower half to the "poser"\"middle" parking lot. should be good fun for the group then the snow get's deep enough that people with 33's or smaller will get hung up\high centered. He also made a comment to me that the lesser rigs should chain up on the lower section. Probably to make it up the hill Gerdo was talking about to get to the middle parking lot. There are several hills actually.
My experience personally is that you either have mud tires with enough tread to really dig or you have something else (i.e. AT's or worn tires), in which case chains will help.
