I didn't know there was an Antietam/Sharpsburg reenactment, much less one in 2020. Glad to see it!
I can't help but notice a lot of screwed up drill, (if they spent two or three hours drilling before the battle instead of thirty minutes to an hour they wouldn't have that problem), but all that aside, even it being a smaller looking event, I'd go up there and attend if I could.
