7/11 We continued across South Dakota with a stop at Wall Drug and into the Badlands National Park. Well worth the stop. We parked the motor home and drove the car into the park. It took us nearly 2 hours for the short loop. Miracuously the coach was still there and we had lunch in a restaurant (only our 2nd meal out on this trip) before heading to another WalMart in Worthington, MN.
