I no longer work at Stevens. Moved home to Montana today, and my plan is to be living here for the rest of the winter, though I do intend to come back and visit sometime during the spring.
Terrain parks everywhere are a community effort. If everyone respects the etiquette and rules, and enforces it amongst the user group, everyone benefits.
Basically, this means being smart and taking the time to educate your fellow park users about what they've missed or are doing wrong. If someone is in the wrong spot, get them to a safe one, and calmly and politely explain why what they did was dangerous and how they should modify their behavior. If they continue to blow it, yell at them. If they still don't get the picture, talk to the park crew.
Respect gets respect. What you put into the park, you get out.
