Clinton did the same thing at the end of his term. It has been the goal of the Left’s elites to reduce the number of common people using the national parks. Especially concerning to our environmental betters are day users and families with children. These are people who don’t spend much money in the park - they pack a lunch and either camp or stay off site.
How to eliminate the common folk who are ruining the elite’s experience? Raise entrance fees, eliminate camping sites, reduce parking spots or move them off site, force people onto crowded buses to free up the roads for those staying in expensive in-park lodging.
Nature and wildlife are only for the King and the King’s men.
But, strangely enough, these are of little interest to many of his core voters.
I don’t know about that. When I hit 60 something, the NPS issued me a Senior Pass for $10 which lets me into national parks for free for the rest of my life. I heard that I get a 50% discount on some concessions also, but I’ve never tried that.
