It's 30 years since I visited Zion. So beautiful. The best part of a trip that included Lake Powell, Yosemite and the Grand Cannyon, though those were all great. Being British, basically no-one here has ever heard of it, so I'm always keen to tell people about it. The Park Rangers were great, too.

Mind you, your President seems keen on deterring foreign visitors of all sorts, so those visitor numbers are sure to decline. So that's a win, I guess.
