Back in the early '80s, when I got out of the service, I tested down in Houston and Dallas but didnt take it cause as much as I liked Texas I couldnt say I liked the heat. I took a combat course in the San Antone area in Jul/Aug in the '70s and I bet it was in the 100's every freaking day. We had a PX that was the only place that had AC and I bet I drank 9 pitchers of Coors every day after coming in from the field. Great state but to dang hot.
I like the entire south but as far as climate goes the high country of Arkansas, TN., MO.,NC.,SC.,WV. is south enough for me weather-wise.
