This was the route and we stayed true to it for the most part.
We only slept in hotels in San Francisco (for a week) and once in Wyoming and once in Texas (San Antonio). The rest of the time we slept in WalMart parking lots in the back of our SUV which had a futon mattress. Each night we had to transfer all our stuff to the front. Some nights it was unbearably hot. But, it was all worth it. We saw so much.
I took photos with both my Canon Rebel and Holga. I'll post my Holga Photos here and give you guys a link to my digital ones.
My digital photos can be found here and our road trip blog can be found here.
Thanks! I look forward to more travel and reading about your travels!
