There’s sites on the peninsula that are pretty much open season, but right now there’s snow up those roads. Check out Hamma Hamma rd and Duckabush rd. At least for me it beats being in a packed campground regardless of having a dog. You’re a little more remote, but isn’t that the point? You can’t camp just anywhere, but when you find a spot, you’ll know it when you see it. That’s what I’ve done. Very peaceful.
