I'd roll with 30%. I just knew there was way more state land that most people think. I would definatly say of the 30%, 90% of that is in the north end of the unit. However, if it got ugly, and I could not get in the unit from the north, I would look at the sr503. Across from Merwin lake is all state land as well. Also, usfs rd 81 (if open) gets a guy real close, then he needs to hike out of the Lewis river into toutle, and do some back packin. The trick would be crossing the toutle and staying dry, or else your not on state land.
