There is NO access anywhere to kapowsin except the main gates. The permits are sold out, but next year ya you can take your kid in. I live close to that gate and it would be awesome if it was open!
I know several people that patrol the areas around here and if you get caught your in trouble, especially if it says permit required or anything like that. You must have a permit, and no quads, dirtbikes, or any type of off road vehicle except a truck.
