Answer from a 145th
I just don't get it. Piney Woods is a month away. Best opportunity to live the life of a soldier in the field for an extended time that you're going to get for maybe the next decade - if ever again - and you're talking about a wish list of 150th anniversary events.
Bigger ain't better. GAC vs. Andersburg was proof of that. You should take advantage of a great event like Piney Woods while there is still time. I have my doubts about seeing another opportunity like this again. As for mega events, there's always another puffed up, mega event on the schedule which doesn't live up to the hype. People keep sayin' they'll never do one of them again and will do a better event next time. Unfortunately, next time never comes and they go right back to the hyped up events for one legitimate sounding excuse or another.
"While the original battle [Gettysburg] may arguably be considered the epicenter of the history of the war, the GAC reenactment is not the epicenter of the hobby. To confuse or equate the two is unfortunate. - Bernard Biederman, 6 July 2012
"Authenticity conflicts occur when reenactors from one end of the spectrum attend events at the other end of the spectrum then try to impose their own standards instead of event standards."
