I recently traveled to Arizona. A friend of mine owns a house about an hour from Phoenix. We went for a week at the end of June. It was hot.. and yes, while I kept hearing it was a "dry heat" (that became a bit of a joke!) once you hit the 40's (100's for my American readers) it is just plain hot. I was surprised how quickly I acclimated to the heat .. but yes, it still was hot lol. That just gave us an excuse to lounge in my friends wonderful pool.
We took a drive to the Superstition Mountains... they are amazing. I would love to go in a cooler season and have the chance to hike out there.
We had a wonderful experience one day while driving on one of the highways.. a way off to the side, on a cliff we could see the silhouette of some wild horses. We pulled over and found a road that led us out to where they were. These horses were amazing.. most were in remarkably good condition. They almost looked like they had been brushed and let out for the day.. but then you would see some of the stallions and see how beat up they were. Scars covered most of their bodies. Beautiful untamed animals. For yes we did try and get closer to some of them.. they were having none of us lol.. the stallion would quickly rush them off.
