As gunslingers feign violent deaths, residents hoping to show visitors a good time are likely feigning interest. Yes, it gets pretty hot. Don't think a dry heat makes 105 degrees the least bit bearable. If it were intended for us to be outside in the summer, we wouldn't have refrigeration. Heat pumps do pump heat, though not very effectively on those rare winter days when residents seek warmth.
Heat pumps are much better at pumping cool air.
But if they were called cool pumps, people would mistake them for fashionable women's shoes. The desert does not blanket the state from Mexican border to the Grand Canyon. With golf courses, lakes, subdivisions and malls, it barely covers the Valley. Farther northward is the Grand Canyon. The majority of Arizona residents are under the impression the Canyon belongs to their state, when such is not the case.
