..I've done Los Angeles to New York with Trek America, which was great. We arrived in New York less than two weeks before 9/11 and I have a sequence of photos which show the Twin Towers getting bigger as we were approaching from the south. Quite freaky in retrospect.
With a band mate, we hired a car and drove from Los Angeles to New Orleans in 2005, when we were playing the French Quarter Festival, and in 2007 we did a round trip from Houston, up to Santa Fe and came back through Texas to Louisiana.
On my own, I drove from Memphis to Nashville, down to Montgomery Alabama for the Hank Williams Museum and then drove all the way to Lubbock for the Buddy Holly Centre and to visit his grave, before driving back across the Panhandle to Memphis, Tennessee where I visited Graceland.
What you can't beat is the feeling of space and scale. Driving through Death Valley, hiking the Grand Canyon - there's nothing like it. Lots of my USA travel photos in amongst this lot -
