Thanks to the economy, my company took on another site (outsourcing their IT) for our client and it brings me to Dallas for a couple of days.... Temps went up about 10F from when I left Iowa.

Spent some time in Dallas (training) about 10 years ago (also in July). Great place for BBQ and steak and downtown was nice but the heat factor was very tough to take. If I was living there today and without AC my audio gear would not survive and nor would I. At least you don't need a snowthrower in winter.
