And in all seriousness, if you decide to visit, say, the Mojave or other desert venues here, take sunscreen and PLENTY of water. It was just a few decades ago that a German family decided to drive out into the Mojave unprepared and they all ended up dead.

There isn't jack shit except for wildlife.
And for fuck's sakes, if you visit Yellowstone, DON'T GET ANYWHERE NEAR THE FUCKING BISON. THEY WILL FUCKING KILL YOU.
