You're absolutely going to love Austin. There are a few ranches scattered even around the airport filled with longhorn cattle. They probably won't be there much longer though as quickly as that area is growing. Just bring lots of sunscreen and be prepared to roast. I almost couldn't believe how hot it still was in early November last year.
Oh boy, I don't handle heat well and my wife is allergic to the sun, so this could be bad.
It was my first time there and coming from a place that already had snow on the ground kind of altered my perception of what it would be like. : ) I was forced to be outside during the peak heat on the day of the shareholder event but it cooled down nicely at night. Early morning/late afternoon was definitely the time to be outside.
