I live in West St. Louis Co. Missouri(Chesterfield) and was fortunate to be able to watch it from my deck at the house!
Didn't get as dark as I expected but the cicadas and crickets were noticeably active..got about as dark as it is just after sunset, nowhere near as dark as midnight as they said it would. You couldn't see the stars either like they said e would...
I have an area of my yard st up with trees and bushes and several birdhouses, also an area setup with hummingbird feeders and a mister...didn't really see anything out of the ordinary with them or my dogs...
Two things that really got your attention was the way the daylight looked and hour previous to it and after...can't even put it into words...and what they refer to as the "Diamond Ring" effect as the moon moves away from the sun, absolutely one of the most spectacular sights I have ever seen...
Very very HOT here, only 92 but oppressive heat with a heat index of 101.... I really didn't notice much of a temperature drop they said would happen, possibly due to the high humidity....
There were "eclipse" parties and gatherings all over the area, just about every park, school, or any open area with a good view of the sky was full of people, kinda cool to see in this day and age!
