Hi guys!
New to the board and excited to get loads of info. My road trip experience is limited in America but happy to help in any way!

A friend is moving to LA in february and we are looking to drive cross country. Something we've wanted to do for ages. We have a lot on the list already, but we noticed there is a big gap. Here's a rundown.

New York
Philadelphia
Baltimore/DC
Memphis
New Orleans
Austin
Santa Fe
Phoenix
Grand Canyon
Las Vegas
Joshua Tree
San Diego
Los Angeles

As you see, the big gap is really between Baltimore/DC and Memphis.
Anything you can recommend along that way is much appreciated... actually, ANY suggestions for that entire duration are welcome!

Thank you!
Michael
