Jason, I just put a list together (based solely on research, NOT firsthand experience yet) on this thread. I hope yinz guys find it helpful.
Alex and I may take our crews for a trip to Ohipyle this year for a wild pawpaw hunt (I have intel on where to go). I’d assume the more the merrier! I also know of a couple decent spots for mushroom hunting but I’m not sure if I want to share those haha.
There is a recently created local park near Murrysville that appears to have a huge amount of wild raspberries/blackberries along one of the trails and a good amount of crabapple trees in another area. A few improvements might be made to some of those trees in the next few years.
