So how do we stop this, or prevent it from getting out of hand?
Not gonna happen. Okla is in a recprical agreement with other neighboring states to not rape the other state for out of state tags.
Hell, it cost me a non resident tag to take my grandson fishing, and beyond my resources to take my grandson hunting for a day or two when he is here for thanksgiving.
I've got twin grandkids from Tx that will be old enough to fish shortly, so if you think the new laws that upped the prices on out of state tags, and did away with non-resident lifetime licenses are paid for by non-residents, are sadly misinformed.
