Yeah the wife and I tryed it the last 2 weeks of July probably 10 years ago.Never made it past Memphis.The heat was brutal.Probably spent a $100 on bottled water in less than a week.We finally quit getting water and would go into a resturant and get a large takeout cup full of ice.It would be totally melted in 15 min.The next time I go it will be probably the end of September.Good luck with your trip.
