So I went to this civil war re-enactment today and wooo i must say, funny stuff happened! They had about 6 artillery guns on the field that were going to fire at about the same time. So the battle starts and they all fire in quick succession. Next thing you know, all the car alarms in the parking lot go off :rofl: :rofl: :rofl: :rofl: I also got a good feeling of the idea that you see things before you hear them :P. There was a few cannons on the confederate lines and I remember stareing right at one and seeing it go off and about a second later, i heard the actual explosion. You also could see the pressure wave on the grass when a lot of the cannons fired at the same time! That was awesome and you actually felt it.
