I'm at Fort Sam Houston right now for AIT, we had a soldier die two weeks ago after his/her PT test. We were told they had been drinking energy drinks. This happened in the early morning mind you when it is reasonably cool like 76 degrees. The temperature has been 100 or greater for a number of weeks now...if you don't drink water you die nothing else can substitute H2O. O yeah Texas is great so much that I can't wait to leave maybe I'll go to Alaska.
