I have a lot of family in Vermont, the green mountaineers are good bunch. Burlington gets nutty though.
I have had a lot of conversations with park rangers in Maine, most of them get a kick out of the hammock. Had to nearly drag one guy out of my HH after he tried it out lol. I even gave a game warden a link to this site.
So I'm pretty sure you shouldn't have many problems regardless of what the admins say.
