Are they? A huge portion of my state is federal or state park land, and people flock to these places to get away from the cities and the suburbs. If Lee had his way, the federal government could start selling lands in places like Mount Rainier National Park or the Mount Baker-Snoqualmie National Forest. These areas host numerous trailheads, picnic areas, campgrounds, and the like.
I can't help but agree with the author of the article, that Lee just wants to sell these lands off to rich people who will deny access. We have a long history in Washington of exploring the Cascades and the Olympics and I want that to continue for the foreseeable future. These lands are the birthright of our children and we should steward them as such.
