Oregon to charge 25% more for out of state RV campers

I would love for Wisconsin to start charging more for out of state campers. I don't think it would deter any of them from coming here. Raise out of state 25% and leave resident fees the same.
Half of the time we go into the parks near us on the weekend, we can't get a parking spot because the park is full of Illinois people. Raise their fees for entrance and camping. Use the extra money to build more campgrounds.
