Just came across this website. Probably familiar to most of you guys but figured I'd share it just in case. They have an ibx for The PA Wilds and some NE and MA regions. Backcountry Discovery Routes (BDR) Maps & Information - https://ridebdr.com/
Any specific areas you're looking into? I can do some gaia scouting while I'm at work over the next few months. Even if my wife can't make it I'd love to come myself.
