I'm new to RTA and could use some help. I'm going from Santa Fe NM to St. Augustine FL in June with my 11 year old boy and 14 year old girl to see family. I'd like some ideas on places to see on our way. Fun and funky is especially good. Any ideas for better roads is good. I used Mapquest. It shows going thru Amarillo, Dallas, Shreveport, Mobile, and Tallahassee. I want it to be fun, not just a very long drive. I'm giving myself about 4 days to make the trip. This is the first road trip I've made without another adult along so I'm a little anxious (?) Any advice would be greatly appreciated :)

Thanks!
