We have a group called Stay the Trail. They are a great organization, do a lot to help keep things open. I've donated financially to them. Went to their website and through the list of all the clubs near me. We have signage on several trails thanking "X" Club for maintaining which I'm down with. I said something in an earlier post about offering to come swing a shovel but that club in particulare only wanted help from members. Life is hectic enough not trying to add anymore mandatory things. I do get the concept of wanting to know who you're wheeling with
Sorry I can't help with the Jeep clubs, I have had the same luck with them (jeep clubs vs offroad clubs) when I tried when I first got my jeep, but if you wanted to clean up the forest I see these guys around me doing work and they just have you sign a liability waiver, then feed you lunch.

I tagged along with a group from FB when I got my jeep for a winter run. Boiled down to 2hrs of watching 2 jeeps do Mini-Moab in rainbow falls (everyone else did the obstacles a few times and was ready to go), an hour parked on the trail talking (???) then turning around on the trail and leaving (did not look fun for the 4door jeeps).
It would be cool to find a fun group like the TJ Fest group. Maybe here, it did seem like the Krew had a busy year this year keeping them from wheeling.
