We were so close! It is probably 30 miles from Richmond to Greenville. My wife and I went to a park. There were about 200 people in an area 500 or 600 feet on a side. People were friendly, it was 73 and sunny with a breeze from the west. On Tuesday, I could not see the sun because the clouds were so thick!
Our back up plans were to go towards Muncie or Indianapolis. A lot of the small towns in east Indiana or western Ohio had big plans.
You should go to the Darke County history (Garst) museum. It has displays about Annie Oakley, Lowell Thomas and Fort Greenville. The fort was about 5 city blocks in size, the largest stockade built in the US. When I was a kid, there were lines painted on the ground to show where the fort was. Walking around it was about 3/4 of a mile.
I heard that 50,000 were expected at the famous Speedway near Indianapolis. I am glad we did not go there. Too much of a crowd for me.
