We are moving from Carlisle, PA to San Francisco on June 16th. Nate and I have to be in San Francisco by the 7th of July, when I have orientation for college. We have no idea which way to go, but we do know that we want to see historical places, landmarks, and take a scenic route. Any suggestions? I don't want to be stuck in hectic traffic on toll roads!

P.S. We are also traveling with our dog, Gilly! (a little wee bit of a mutt :) )
