Hello and welcome back missmeow !
I would suggest you take a look around the site and study a good map and see what the main attractions are that appeal to you. Where for instance would you like to travel south to ? You could start out from Vegas and include Bryce and Zion and Monument valley and head further south creating a loop. Arches and Canyonlands NP's near Moab are also main attractions, and betwen those and Zion and Bryce is Utah scenic byway 12 and Capitol Reef.
You could use Denver as a start point and visit the Four corners region, heading south into New Mexico, like we did here. Perhaps you mean New Orleans etc ?
