I'm reading about the looming government shutdown and that all national parks will be closed if the shutdown goes into affect. My question specifically is I have my first vacation to yellowstone planned for 2 weeks in May. Does that mean no entry to the park will be permitted or that only no services such as restrooms,park rangers and visitor stations will be provided? Do the west and north entrances have gates that can be locked to keep visitors out of the park? Assuming the shutdown happens friday and there is no entry to the park permitted, how long would you wait before cancelling plans and going someplace else? Any information or opinions would be much appreciated. I'm scheduled to fly into jackson hole May 4th with the intention of spending full 2 weeks in yellowstone and grand tetons. Obviously if I can't enter either park I will need to start scrambling soon to find a different vacation spot and eat the plane tickets change fees. Thank you.
