Hot Tamales!!

I haven't figured out why both the busses and department stores find it so hard to adjust the air temperature daily?? It's Texas, the weather changes constantly! I've only been on the bus a short while and people are tinkering with the air vents that are not blowing anything but warm stale air! People are ripping off layers of clothing already! Praying we arrive before the big girl gets necked! Hope there isn't a riot when the heat insanity kicks in!
