Mainly drive to put-ins for BW trips or Quetico trip via Prairie Portage.  More variety with Wabakimi Project trips: Beaver or Otter flights; once a return trip with canoes held down on skiffs that saved us some rough paddling on Caribou lake, followed by truck shuttle to Armstrong.
    Last hiking trip to Isle Royale ('06 ?) wife and I drove to Grand Portage and caught the boat over... much shorter than going from the Houghton side.
