It’s a reality you must face relatively quickly if you move to Arizona: it’s hot. I’ll subscribe to the common rebuttal now: Yes, it’s a dry heat. But that doesn’t negate the fact 10 minutes outside will dehydrate you, or 3 minutes in the sun will give you a nasty burn.
Most people know this, and that makes indoor activities all the more important. Movie theaters, malls, pet stores, etc, all fill to the brim on warm Arizona days. Another option for those who like to wager, is the casino.
