From the Appalachian Mountain Club:
Every year the AMC’s White Mountain Trail Crew replaces weathered or out-of-date trail signs with new signs. The old signs are collector’s items, having guided thousands of visitors for many years along celebrated paths throughout the Whites.
All proceeds from the auction will support AMC’s trail efforts in the Northeast.
This year’s auction is taking place on eBay and will run from Tuesday, November 25 through Friday, December 5, 2008.
