First time poster here.
I will be driving on i90 through South Dakota to Napa, CA a week from now. We are driving in a Honda Civic, so we are inclined to avoid bad weather. We have about 6 days to make the trip. Any thoughts on cool places to stop, roadside attractions or routes. We were thinking of going through Yellowstone if it isnt snowing.
We plan to see Mt. Rushmore, the Badlands, Minuteman Missile Silo, Jewell Cave , and Custer State Park.
Thank you for your help.
