First it was 48 states in 30 days in Summer 2005.
Then it was the Great West in Fall 2006.
So, for Spring 2007 my folks and I have once again packed up for a 2 week road trip. This time we're going to see Utah and all of its National Parks. We're also taking routes so we can see some California National Parks, as well as the desolate central Nevada terrain. (Planning thread is here)
