Just to give you an idea of how joyful Las Vegas is in the summer... the following photos. The first was taken at about 5pm and it was 109 degrees. I had just gotten out of my car (parked in the drive) and I wondered how hot it was in the car. I placed the temp sensor in the car and it got up to about 146 degrees. I took it out and put it back into the shaded carport and got a high of 116 degrees around 6:30pm. Today it was even hotter. It is a dry heat, as they say, with a humidity that hovers around 10%, but as I write this at 9:30 pm it is still 100 degrees. It is impressively hot.
The first year we lived here one of my kid's plastic cars actually melted on the back porch (it was a black car)-- the little roof caved in on itself and the windows bubbled out. I was impressed.
