Bachelor Party Ideas - Eastern UP

We're planning an early summer bachelor party in the eastern UP and looking for ideas of things to do for a weekend away. My current ideas involve boating on the St. Marys (have access to a cottage on the water) and hitting up the Casino in the Soo. Anyone have other suggestions (like are there any dirt tracks, paintballs arenas, etc) south or east of the Soo/that general area?
