The Awesome Virginia Highlands

Grayson Highlands State Park
Mount Rogers National Recreation Area
the VA mountain towns of Damascus, White Top, Taylor's Valley, and Konnarock
the TN mountain towns of Laurel Bloomery, Mountain City, and Shady Valley

and a side trip to the Black Mountain Grassy Cove area of the Cumberland Trail on the way home (can't wait til that trail's done!) 

70 degrees and sunny skies
4 days with kids, puppies, and green grass
nothin' to do but stroll, lay around, read, and rock scramble

It don't get much better than that.
