This summer my wife wants to go see Mt. Rushmore, my daughter wants to go to Seattle. A few years ago we did a trip from Vancover Canada then east and down to Glacier NP to Yellowstone and then back to Seattle through Spokane.
This trip I would like to see some new places. We will fly to Seattle pickup a car and work our way over to Rapid City. From there we will drive back home to San Francisco. We won't be driving up from SF to Seattle because I want to save some driving time and we have been up and down that route fairly often.
We have 15 days in all, any suggestions?
