Man, you ain't gonna get any respect from Texans, talking like that! I say you do one summer's penance with no a/c to make up for it. LOL
I have spent 3 summers in the DFW area (I travel for a living). It is pretty bad (which is why we closed in August but waited until October to move), but that is why God made central A/C :)
Smart move (no pun intended). After being here for six years, I've grown to have a deep and abiding respect for those Texans who toughed it out here before the advent of central air conditioning. I work outdoors, and during the height of the summer heat, I often wondered to myself just how they did it. They were some seriously tough people.
There's a good reason for the tradition of the siesta during the hottest part of the afternoon. You don't fight the heat, you work around it.
