I have the 15th Edition of the "Circuit Hikes in Shenandoah National Park" booklet put out by the Potomac Appalachian Trail Club. There is a 16th edition out now, although I'm guessing it probably doesn't contain much new information.
For all practical purposes - it's new. I believe it runs about $10.
If you want it, I'll send it to you for FREE.......but I do ask that you cover shipping which will probably be $2 or so.
First one to PM me gets it. CONUS only.
