Arizona-Sonora Desert Museum stays open after sundown on Saturday evenings all summer long as the nocturnal creatures of The Living Desert come to life. Look for Museum Docents and Jr. Docents interpreting live animals, celestial desert skies, fluorescent minerals, animal eye shine, Sonoran Desert insects, night sounds, bats, kissing bugs, scorpions, and/or rattlesnakes. Aug 18 - Creatures of the Night - Start your weekend with an evening at the Arizona-Sonora Desert Museum. Find out what creatures party in the nighttime. Spend time with the animated animals and enjoy the popular Live and (sort of) On the Loose show.
