I have now reached Pennsylvania and the dreaded " rocks" everyone talks about. Apparently there are miles upon miles of trail where a hiker walks on rocks with very little ground to put your feet.Some of these rocks supposedly move when stepped upon. Others are jagged and sharp, poking and gouging the feet when you step on them. many claim they ruined a pair of boots..... just in Pennsylvania. This state contains 230 miles of the Appalachian Trail so I hope it's not as bad as they say !
