One other thing PA is known for are the copperheads and timber rattlers that hang out in the rocks. We were at a shelter just inside the PA border one morning when Chris had just gotten out of the shelter and onto the wood platform below. I’d just let the air out of my mattress when I thought I heard someone else letting theirs out too. Chris looked at his electronics bag thinking it was making the noise, when we looked at each other and I said that I thought it was a snake. Sure enough, right behind my boots was a timber rattler, pissed off that we’d woken up. Hah!
