I was at a conference in AZ once. Tucson I think. Sitting at the pool. Totally cloudless sky, then all of sudden these Monsoon rains!!!!!! Whiskey, Tango, Foxtrot... what the heck is this... Lasting a minute or so... we’d be drenched....
I was at a drive through in Phx when a dust/sand storm (haboob?) blew in. The guy in front of me was getting a vanilla ice cream cone. By the time the lady handed it to him out the window, and he took it in his hand, it was brown!
