But wait! There's more! A gila monster has a ridiculously painful and venomous bite and they can hang on for twenty minutes. Arizona is home to one of the only deadly scorpions in the world. The sun is so fierce here we found sunscreen dispensers in the restrooms of an outdoor museum. And don't get me started on tarantulas. Yes, I know their bite is no worse than a bee sting, but just looking at one could give this arachnophobe a potentially fatal case of the willies.
