I have a season pass already, I would also be willing (assuming I can make it on the weekend picked), bring a grill and chip in on food. I would honestly come out and pick up trash without someone giving me a free pass or food. This is our playground, even if BLM does not seem to be concerned with the cleanup we still should. I would rather clean it now without support, then years down the road lose it and wish I had done something sooner.
Not to mention, I would get to hangout with great people and get some riding in.
