I'm from New Zealand, which would be roughly the size of some of your back yards. I'm going on a month long trip to the US. A few days in Los Angeles, then off to see family in N.O. I have a crazy idea that since I have the time, I would much rather rent a car and drive it than fly. My basic information from google maps lead me to the following plan.
Day 1 leave LA drive to Scottsdale, Az
Day 2 Drive to Las Cruses NM
Day 3 San Antonio Tx
Day 4 Houston Tx.
Day 5 Get to N.O.
I've been generous and not scheduled no more than 9 hours drive a day. I'd love some opinions.
