I can only speak for myself, but I think the recent negatives in the GAC events have not only driven their numbers down, but have created a sense that history is being sold rather than enjoyed.
I think that several factors will play in here. First, the date. We will be able to do Gettysburg and still have the 4th weekend to enjoy with our families. Second, it will result in a better and larger (presuming they dont limit the pre registration numbers too severly) event in every way for all of us to remember. Third, it will also deprive the PAC/GAC folks of the significant numbers they are speculating upon. One well known G'burg merchant told me last year that they were expecting and getting ready for as many as 80,000 participants. In this sense I feel bad for for those good people among them who might have wanted a giant event for history to remember, but, the Gettysburg merchants will still their big week, although a week sooner than they expected.
But, in short, my gut feeling is that not just the eastern units but in fact most units will skip GAC in favor of BGA, if they must choose between the two. Further, some will do both! But not to the numbers GAC figgered on.
I am astonished to think that folks think dual events are a good idea, but, Shiloh was pretty good.....better than we expected. For that reason I think BGA is on the right track about G'burg.
After it's all over I expect your unit will find that the BGA event will be (was) the better of the 2/4/?
