120 has got to be tough. But once in a blue moon, we'll get a day down here where the air will be dry but the temps stay around 100. I work outside all day and I love those days. When your sweat can actually dry off, it feels amazing. Most of the time, my hot sweat stays on my skin until I can dry myself off with a towel.
My biggest problem with the high, dry heat? I usually get dehydrated. I rarely feel thirsty because it feels so much better and then all of a sudden, I realize its too late and I start showing signs of dehydration.
