Apparently for Gettysburg the one in late June is suppose to be less commercially oriented, and I was originally considering that. Yet in looking for hotels months back, I ended up ruling it out. Not interested in what I've read regarding the one in early July, apparently quite the carnival atmosphere, and even last year's event bottles of water were being sold for $4 each.
Think I'll wait till this the season is past, when I can catch it again with less people around, like I usually do. Been there many times, and it never gets old for me. Its quite the speical place. About the only thing comparable to me is visiting Independence Hall or maybe a National Park. If you go to Independence Hall, know that its best to get there early before it opens so you can be part of the first tour or two. Otherwise the lines tend to be way too long, and I get quite grumpy about lines. But I digress. In all my trips to Gettysburg, I continue to find new things to see, and enjoy going back to some of those I've already seen.
