We are planning a trip from Northern Florida to Northern California. We would like to take a northern route to be able to travel to Mt Rushmore area. We would like to leave Florida and start traveling North/West. Not interested in heading up through the Carolina's way. Our plans are to spend a total of about three weeks from start to finish. Once we reach California then we want to travel from San Fran down to Montaray (do the 17 mild drive, Aquarium) then a bit further south before starting the trek home. Any suggestions and must see places on the way to and fro would be greatly appreciated!! Hopefull, this adventure will be in late May/early June, 2012.
