Yes, the Great War Association (GWA) has a location in Newville, PA, southwest of Harrisburg. Gun ownership laws are much friendlier out there than they are in NY. My brother was always a history geek, and for years did the Civil War living history reenactment thing. I did a few of those with him. Cool....but kinda boring unless you were really into the history of it. Those events were more of a show for the public.
Of course, he knew a lot of like minded history and military types who love the history of war and weapons. He transitioned to GWA events, and now has multiple period kits, including weapons, for WWI, WW2 and Vietnam. The events they have there aren't for the public, it's to immerse yourself in the history and the battle. Yeah, they are only blanks.....but when making tactical movements and engaging in combat you really get a feeling for what it may have been like to be in the trenches in WWI, or on patrol in the jungles (woods) of Nam. Lots of Vets at the events as well. Being in a foxhole with a guy who just got back from Afghanistan a year ago....the shit guys like that have been through, the things they share....it gets very real. One of the Nam events....a Vet from Vietnam (not participating in the event) saw a sign on the main road outside the complex for 'Nam '69' and wandered in. It was kind of surreal. So, in addition to gaining a much better appreciation of what people went through in war, it's a hell of a lot of fun doing drills, engaging in combat, and shooting real guns, heck....even pulling KP duty to cook and serve in the field mess.
We REALLY need a proper roll eyes emoji!!
