I really enjoyed seeing this museum the, collection of items is huge with unique pieces and so many items to look at it spans revolution through Korea. However I am giving the low rating because the museum is in serious need of upkeep. Many displays are growing mold inside and items seem to be falling apart from mold growth is very sad to see these great items deteriorate. The building also smells of mold which makes me wonder if it is even safe to be in the building. We went on a 98 degree day and I thought it would be nice to go in building and cool off but I think the only air conditioning is one window unit we were still sweating inside. There was only one employee and he was polite but seemed very weird and off putting. I was here as a you g adult and remembered it being much nicer. I hope they can get funds to clean and restore the displays and make it a five star experience again. If you really want to see a lot of unique military items it is worth the seven dollars, but I think your time is spent better elsewhere in Gettysburg and I'd skip this one, while it is a cool collection it feels depressing it seems no one cares about maintaining this museum. Even in the parking lot I know pavement is expensive but it wouldn't be hard or costly for someone to spray all the overgrown weeds. I hope they make improvements soon.
