Leaving around 20 of August from Port St Lucie Fl to Phoenix AZ using I 10 most of the way so the gps says, I never travelled that route any interesting sights along the way I am in no rush. Thanks
Zgypsies and Laman gave you some good ideas. Even given that, I’ve made that trip a couple of times and have to say it’s the most painfully boring drive I’ve ever made anywhere. Another option would be to go to Mobile then cut NW though Dallas to I-40 and come into Phoenix from the north. Surprisingly, it’s less than 100 miles difference over I-10. The plus to me would be the southern route will be hotter than blazes in August and I get more heat than I ever want.
