If you take a picture and send it to the forest service in cle elum, they can elect to send them a ticket, they actually like handing out tickets to the click clicks, Or you can call the sherrif office and report the violation. It's better to educate them than fight with them. I did have a skier pull right up to my back door of my trailer last year at GC, I left them a nices / semi nasty note saying that next time they did this I will remove all 4 valve cores on their tires. have some courtesy I told them.
I LIKE your thinking 'bout the tire valves!
