I live in Easton,Pa. It's on the New Jersey border. I just started getting into varmint hunting myself and found it hard to find a place also. I don't think the game commission has any land just for groundhogs but if you can find them (groundhogs) on state land you can hunt them. Your best bet is to find a farm and ask permission to hunt. I'm 23 but only look i'm 15, so a lot of farmers have their doubts about letting me on their land. I got lucky and went deer hunting last year with a friend from work on some private land and the landowner invited us back for some groundhog hunting. The restrictions for grounhog hunting is the same as small game except you have to wear a solid blaze orange cap. Good luck.
