If you spit on the sidewalk in Vegas or Phoenix, its still there 2 years later along with all the other dirt rocks and varmints.
I love the dry desert heat in Arizona where I grew up, compared to the heat and HEAVY HUMIDITY in Florida where I have lived for the least five years. Completely insufferable, near impossible to tolerate working outside in the summer. Bugs everywhere.
I used to play golf all the time in Arizona in the heat of the summer. Hot but tolerable with some occasional shade and a breeze. I cannot play golf here in Florida in the summer without taking three changes of clothing and losing 10 lbs of sweat. Did it once and it was the most uncomfortable round of golf ever. Soaked to the skin. Even ruined my shoes with standing water on the course. Never again. I'll play in the winter season from now on.
Phoenix is supposed to be 118 degrees tomorrow. From experience, that'll be much more comfortable than the 95 degrees and 85% humidity forecast for today here.
Hah! Spit in Phoenix and it will evaporate before it ever gets to the sidewalk. We call it “verga”.
