In view of the eclipse on Monday and being told that 600,000 people are coming to view the eclipse I looked up a few facts. Wyoming is the 10th largest state in area and the least populated state with 6 people per square kilometer. The estimated population of Wyoming for 2017 is 595,153. Liz's husband tells me we will have 98.02467% here.. I will be in the house, I think. They also say on Monday there will be a plane landing at Cheyenne airport every 2 minutes.
