I'll take our cold weather over the desert heat any day. It's so much easier to warm up than to cool down. We lost one of the residents of our townhouse community on the weekend due to the exact same thing, cardiac arrest due to heat exhaustion. And she was just sitting around the pool watching her grandson swim. Honestly, deserts are probably the environment that scare me the most. If you get lost, and can't find water, you're screwed.
