Went to the Nahatlatch this past weekend.

The road, although dirt, wasn't too bad. There are not many places at the lakes for trailers but the riverside has lots of nice spots and is outside the park boundary which means free - or $10/night at a Forest Service site. Hope to get some pics up.
I want to make the trailer more 'off road worthy'. Their are too many beautiful spots like this off the beaten path in BC.
