You guys, and your downhill, back country, and all of your big mountains.
I ain't got jack shit to work with here in Ohio, except park, and that is pretty much all there is to do.
I feel ya. Here in Minnesota one of the (arguably 'the') most extensively equipped park has a vertical of about 200ft. With a rope tow, that means you can literally take a run a minute, which sounds nice until you realize that everybody else can to, meaning that every feature has been hit hundreds, if not thousands of times by noon. Dropping off a box into a 2 foot deep ice trench is less than enjoyable.
I've seen air rifles with integrated silencers like sort of like that. The only problem is convincing the big wigs that a suppressor affixed to a removable barrel does not constitute a removable suppressor.
