I was driving back to Tucson from Idaho in the summer of 1993 with some friends from Germany. I had to get back to Davis-Monthan AFB from leave and they wanted to see the southwest in the summer. I warned them it would be like nothing they'd ever experienced. It was around noon and we were driving by a bank sign in Phoenix, and it read 112°. I looked at it and mentioned how glad I was for A/C. They looked too, and kind of shrugged. Then the signs flipped to 44° Celsius and they freaked out. They made me stop so they could take a picture of it.
Sorry, wrong year. It was the summer of 1992 when we went by that 112/44 sign.
