Just a thought, but there is a car show in Bethel during the last weekend in August. Beautiful area to drive in the white mountains. Perhaps a Land Rover contingency could appear for the show, and then a trip to the top of Mount Washington. If anyone knows the area well enough, there are several logging roads etc. that could serve as a nice off roading trip as well. Rooms are plentiful through Sunday River Ski resort, or there are campgrounds not far away.
