My family and myself are thinking of taking a road trip to Rapid City from Louisville. I passed through Rapid City on a road trip to Seattle 6 years ago. We drove through Wisconsin and Minneasota the last time. I am wanting advice on what routes to use. Also I would like opinions regarding wether I should rent a car or if using the family 2000 Nissan Quest van 131K, but well maintained ,would be okay. Plus any advice regarding sites to see, tips on dealing with two teenagers in the backseat. It has been a while since we undertook such an ambitious adventure.
