I'm planning a road trip from New York to San Francisco with my roommate. We've got three weeks and we'd like to see as much as we can on the way. Out idea at the moment is to drive through Chicago, through some of the National Parks into California and then back...somehow. Not sure of the return route yet. Any recommendations? Is this plan even feasible?
Additionally, if you know of any inexpensive, relatively clean & safe places to stay please do tell.
