Arizona Sonora Desert

I spent most of my life living in the Arizona Sonora Desert. Here is a short description of the desert from Wikipedia: Sonoran Desert.

The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi). The western portion of the United States–Mexico border passes through the Sonoran Desert.

The desert contains a variety of unique and endemic plants and animals, such as the saguaro (Carnegiea gigantea) and organ pipe cactus (Stenocereus thurberi). 

Now that we have moved to the mountains of Utah, I think the two places are a toss-up.  Snow in the Winter is nice. Heat in the Summer is also nice. I like both.
