Day 4 - Sturgis to Mitchell SD - 600km

Another good day on the road, althugh with navigatort Mike and his side kick Rog-rog, making a few errors starting out..we went round in a few circles..all part of the fun. We then had a side trip to Mt. Rushmore to see the 4 presidents. What great roads on the way in, although hilly, but lots of curves, and we took the back way out via Hwy 40 which was another good Mini road. We stopped in Wall to see the famous drug store after reading the 252 signs posted along the way.. we saw the first ones in Montana, a couple in Wyoming, but the most are in South Dakota. We had a nice lunch there, cleaned off the multitudes on bus and headed for Chamberlain to see the Akta Lakota museum, where we cleaned even more bugs off the cars! By now the temp is up to over 30 degrees, (86 F) so we were running hot..not the cars, but the people, other than the new Mini who were being windswept by the air conditioning! We ended the dat at Mitchell, home of the Corn Palace.. and spent asome time fussing with the Cooper S which astarted to run rough. we found the exhaust pip has been wacked enough to bend the clamps and deform the new pipes, probably from one of the road to bridge bumps we hit earlier in the trip. We solved the rough running with a setup of the points, which had closed up the gap and were too tight.
