A game on there called Turbo Cups is a riot. The first time I saw it I thought the people playing were just a bunch of jackasses (this may be because I was sober at the time), but I have since played it and got completely f'ed up playing it. Becuase you must do something of skill and race - it gets pretty interesting as the night goes on.
Good luck with the bear games. DON"T PLAY WHILE BOATING!
