Moose Creek strip.
Last weekend, the water was crazy high, and chilly, but the area at the NW corner of the confluence of Moose and the Selway has a huge eddy that made for fine swimming (at 97F!). There was not that much traffic last weekend. Parts of the strip had grass up to the side windows, but both runways have been brushed out to 12' wide by all the other Lycoming powered weed wackers. You can use the middle third of the main runway where the grass is short, and the best parking/camping (shortest grass for tiedowns) is still in the old sign area west of the intersection.
