I was thinking the same thing - we need to head north!
A few years ago I went with a group and camped near Happy Jack & Clints Well. One day we went to check out some very remote cabins that are like time capsules - they were all locked up but no signs of vandalism or anything - it was amazing! Then on the way back we stopped to check out Potato Lake. The next day we took another back road to Blue Ridge Reservoir and we did some kayaking, hiking, swimming - then headed home. I'm trying to see if I can find those cabins again. But even if I don't there is plenty of awesome things do to and see up in that area.
