National Parks are excellent targets for exploiting budget crisis. I remember 2013 Obama/ Healthcare vote pressure, and shutting down all National Parks to inflict pain on populace. Friends from Colorado had planned their final trip to Civil War Battle fields. Drove RV 3 days and arrived the date park gates were closed. The wife died shortly thereafter. Never got to see then, tho it would have been simple to leave the gates open and hire a local to dump the trash.

Yes, I have canceled some trips and would recommend it, because those pulling the strings have never even desired, or been to a National Park to enjoy camping, wildlife, great views. What do they know, or care? We're not on their radar. (Or wavelength).

Do what is in your best interest. Don't spend thousands of dollars and weeks on the road, to arrive at a locked gate.
