On another note, finally heard back from the state park volunteer coordinator. She game me a list of state parks near me that my need some help clearing trails. Also told me about a new-ish state park near me that's cutting new trails. Now all I have to do is convince the park ranger there that I'm not a total idiot and massive liability lol. With my luck I'll be relegated to using hand tools while the chainsaw stays in the truck.
I volunteer with a National Forest. Maybe not the same, but you can volunteer directly, or as part of an organization. Organizations are much more popular than individual. Also we have to do their chainsaw certification program and have a current CPR/First Aid card before we can run a chainsaw on their projects.
