A buddy and I want to try to do more winter camping this year, but we're both kinda new to the area and aren't super familiar with all the regional weather/elevation/closures quirks. Last year when I researched it, it seemed like I could only find closed roads. Any reliable areas that stay open in the winter? Not super set up for off-road snow driving so hopefully things below the snow line. Preferably within a couple hours of the Seattle area. Thanks!
