Ho boy, now that is where you are mistaken. I do know heat, my folk's idea of a good summer vacation back in the 60s was to load us up in the vintage Plymouth Valiant station wagon and drive from northeast Ohio to Panama City on the Gulf Coast of the Florida panhandle. My grandfather had a place there. He stayed in the winter and came up north for the summer. We would go down for a couple of weeks in July. Your description brought all those memories crashing back. I'll take the dry heat every time and you are welcome to my share of the southeast, couldn't drag me down there with a team of mules.
Glad you take care of yourself and your crew and no, water by itself is not enough!! People up here think I nuts for wearing long sleeve shirts. I've got one of those caps that have the back and side curtains. Lets me wear my mickey mouse ears (with built in speakers that let me listen to music or audiobooks via a bluetooth) while I'm working and keep the sun off my face, ears, and the back of my neck.
Stay safe!!
