I did a summer Vaca. in Az in mid-July years ago for 2 weeks with the wife & kid. Yeah; it was HOT but like you said, a dry heat so to me not nearly as bad as say Fla in July with soul-sucking humidity. The one thing I remember though was the pool at a hotel we stayed at in Lake Havasu was as hot as the air so it was virtually pointless going for a swim 😆 We had a blast though. Grand Canyon, Lake Havasu, Yuma, 4 days at a dude ranch in Tucson (my ass still hurts from that one 🤣), Parker Az then ended in Laughlin before flying back from Vegas. That was one of those trips your remember forever! Had a ton of fun!!
