My 58 yo husband and I are fulfilling one of my goals of hitting all 50 states. For my 60th on January 20, 2018, we are flying into Sioux Falls, SD, from Orlando, FL, to drive to Mount Rushmore.We arrive around 930 AM on Friday, will rent a car and head West. What should we see along the way since we have a 5.5 hour drive we would like to break up? Should we drive the Badlands Loop? How long does that take? Hubby is a veterinarian and I am a PT.We cannot hike, but a mile or so since I am a cancer-survivor and he had a hip replacement 3 years ago, but we love nature/animals! On my birthday we plan to see Mount Rushmore. Is there a dinner show you would recommend for Saturday night to celebrate? What should we do on Sunday before heading back to Sioux Falls that night?
