The Appalachian Trail at Caledonia State Park

In Bill Bryson's book about the Appalachian Trail, A Walk in the Woods, he is exceedingly critical of the Pennsylvania portion of the long path from Georgia to Maine.  Never mind that he gave up actually walking the trail by the time he got to the Keystone State.  Never mind that what little walking he did was in short, disjointed segments.  Never mind that he mostly just drove around in the vicinity of the trail and complained about how disappointed he was.  He really didn't give it a fair shake at all.  And yet, one of the few areas where he actually walked the trail in Pennsylvania was right here at Caledonia State Park--which is on the northernmost outcroppings of the Blue Ridge Mountains, just west of Gettysburg. 

I walked the trail here with my daughters, and he's right.  It's very rocky.
