ICBM Silo

 On our peregrinations in Wyoming, South Dakota, Nebraska and Colorado, we stopped by a Minuteman silo near Wall, SD.  

Things I learned:  The fenced-in area of the silo is pretty small.  My estimate, 1/4 acre.  The silos are unmanned, the control area, where each of the officers have a key and need to turn them at the same time, etc. is remote and controls 10 silos.

After seeing the layout, I spotted 3 silos on the way between Hot Springs SD and Denver.  We took a back way through Nebraska, which we theories was the mapping app avoiding traffic.  Even though I knew the route we took, it was still pretty hard to find one of these three on Google maps.  Here's the aerial view.
