I wouldn’t be so quick to judge. I was at Manassas several years ago, talking to a couple Rangers at the visitor center, and a family comes in all excited and wanting to know where the reenactment is. Rangers tell them there’s no reenactment that day, but the father (with wife and two sons nodding in agreement) is adamant that they heard massed musket and cannon fire coming from the direction of Chin Ridge. The Rangers tell him again, no reenactment, and one of them leaves to go investgate the reported gunfire. The other one looks at me and says “we get these every week or two”.
Apparantly the big occurances are the people either thrilled or absolutely apalled at the realism of the Civil War medicine living history demos at the Stone House that happen regularly, but again without any such thing being on the schedule ...
