My brother lives south of there and is freezing his butt off. He has six acres of parking if you need help, PM me for details.
I picked a deuce out of there last April and they were very nice to deal with. If it is running and off the lot there is plenty of parking if you head straight out of the DRMO lot and turn left past the row of wearhouses. You can spend a little quality time adjusting mirrors, airing tires and getting things sorted out and not bother a soul.
I think if you go out the gate and just up to the left there is a fueling station with diesel and air as well. That is a high crime area, there are close freeways and plenty of 4 and six lane surface streets to get you away from there and on the way home.
If you are driving it all the way to Florida, maybe an overnight in GA before heading home would be best? I cannot commit my bro to work, but he was a heavy truck wrench in the army and has been an ASE certified everytrhing related to trucks ever since. In a pinch he might be able to lend a hand or at least get you parked well south of Atlanta for the night.
