Also, if you want the routes to be a bit more variable, something I'd suggest is looking at [url=http://traveluso.com/wp-content/uploads/2014/02/routes_rough_map.jpg] Amtrak [/url] train routes... They span a lot of the US, I used the train all the time to get home when I was in Pittsburgh for college, and my grandmother and her new husband go on nearly monthly vacations by just picking a random Amtrak station and getting a ticket.
