It does affect them negatively though. I remember back on the movie, "City Slickers 2," the entire picture was originally going to be filmed in and around Moab. The local enviornmentalists made such a huge deal about the damage a movie crew could do, that eventually they just shot the most necessary shots in Moab, and went elsewhere to do the rest.
Now a movie of that size literally brings millions of dollars into a community, over a period of just a few short months. But because there was a chance the crew could disturb that special real old dirt I, which I can never remember the name of, the enviormentalists won, and the crew took thier money elsewhere.
Now, I'm no expert, but it seems to me that a bunch of professionals who have been warned, and have an enviornmentalist paid to be on the crew full time to make sure nothing is harmed, is gonna do a lot less damange than 20,000 jeepers on a weekend party.
My worry is that if a few people are capable of turning away that kind of capitol in order to make a statement, then it's very possible that they might be able to pull the power to keep closing trails, get rid of tourism, and create their little world just the way they want it. I really hope not, I love Moab. And many films continue to go there, but always with a hassel. I just hope that we can continue to enjoy it, and a few people don't mess it up for everyone else.
