Day 50 Badlands National Park to Mitchell, SD
Last evening there was a stargazing show at the park amphitheater. The presenter was very good and used a series of slides to show the relative size of the planets and stars. Our sun is puny compared to many other suns. He then turned out all the lights and used a 2 mile green laser pointer to point out various stars. This worked really well and made it easy to follow him as long as you were close to him.
This morning we relived the cold war at the Minuteman Missile National Historic Site. We had a guided tour along with 10 others. The tours are booked months in advance but we got there at 8:15 am and were wait listed. At 9:00 when there was a no-show we got on the tour. The tour took us through the living space and control center for a cluster of 10 missiles. The tour guide was very knowledgeable and covered the many strategies to ensure annihilation of the USSR in the event they fired a missile at the USA. There are still 500 nuclear missiles on alert in the Plain States.
The rest of the day was driving east on I-90. I thought we would have seen the last of the motorcycles but the rate of motorcycles heading east away from Sturgis was 1 every 12 seconds.
