The best I've been able to do so far is to write a couple letters saying as politely as I could that the most depressing thing I ever see in the wilderness isn't trash, and it isn't trampling... it's fences and "NO" signs - especially when they say "NO" to something I've personally done there (legally, harmlessly) in the past.

In any case, if you're interested in 45 minutes of video documenting the drive from Vulcan's Throne to Las Vegas here's a little film http://youtu.be/2lvZIXUNF1w
