I think it's getting close to tapping time here in PA and I'd really like to do it. I was wondering if anyone else does it, and if you know of any other types of trees that can be tapped. Since I don't own any of those types of trees, I have to get permission from someone who does. I've got permission to tap one tree. I contacted DCNR (I think that was the agency) about tapping some trees on some nearby state hunting lands, but that was a definite no. Sure wish I had my own trees! Sweetener would be invaluable if the event of an economic collapse.
