What strikes me as the most significant opportunity afforded by the GET is the opportunity for a big circuit hike.
When the Schuylkill River Trail is complete, Matty will be able to hike from Philly to Port Clinton where he'll be able to hike the AT SOBO to the GET NOBO to the AT SOBO to Port Clinton. He can celebrate completing his circuit hike at Port Clinton Hotel before heading back home without spending a penny on gas money.
Or maybe cross over the river after taking a part that's done, to the Horse-Shoe Trail; over 60 years of REAL yellow blazes from Valley Forge scratching the bottom of The Green Diamond on its way to, um, well let's say, the Doyle. (Camping restrictions and roadwalks? Maybe a few...)
