Let's start off by saying Jeff is an extremely helpful guy when it comes to asking about information on creeks and hikes in Nepa. The new edition of his book for hiking in the Endless Mountains has more detail, not only in GPS coords, but also in some color pictures, as well as new hikes too. If you live in Northeastern Pennsylvania and you like to do more than sit on your couch, this is an excellent read to show the beauty that most Pennsylvanians don't even know exists in their own backyards.
So c'mon, buy a copy, get out and explore the natural beauty that most people take from granted. You won't be disappointed with all that there is to see and do in this book. My personal favorite area is SGL #13, lots of great scenery and waterfalls. I've been hiking those runs for years and always find something new.
