Get on a dang plane ya dummy, get there quicker and have more time with her!!
This all day , every day . AL to AZ is a looooooong drive! And doing it alone , hell naw. You're gonna spend 1/2 your time driving. But if you have to drive , go to Memphis on US72 , get on I40 West and keep going and going toward the sunset. Good luck , drive safe , watchout for IDOTS.
This is the route my son drove out to Phoenix with his friend to MLB spring training. With the two of them it was a heck of a drive spending the night in west Texas. They did drive back non stop the year Covid shut everything down. You are going to be tired, good luck and be safe
