WINTERSPORTS -- Every group has its share of dipsticks who cast a bad light. In this case it's one snowmobiler/snowbiker who snubs a sign and common sense to ride up a snowdrift and over the recently restored roof of an historic structure at Mount Spokane State Park.

Holly Weiler, who's volunteered hundreds of hours of labor at the park, had this to say as she snowshoed past the structure and snapped these photos:

Oh, no. Historic structures in State Parks are NEVER to be used for jumps. We put up signs a few weeks ago in hopes of politely informing people who didn't instinctively know they shouldn't do this (and that off-trail travel is illegal besides). But now this. Not good.
