Call us crazy, but my family and I just love the 1000-mile drive to Florida: the stupid sing-alongs, the smell of day-old Cheez-Its, the thrill of rolling down the windows to that first blast of tropical humidity.  But we're not complete wackos. We only love it in one direction.


Unfortunately, right now their website still points to their November/December issue. But keep watching http://www.aaaworld.com/ for the update to the January/February issue.
