I'm a concerned

I have always been a believer in spirit, and at times spirit reveals itself to me.  When I was recently at a museum to see a fashion show, I took this picture and look what shows up.  When I went to take the picture, the green light was actually moving around.  I thought it was just some reflection and just snapped the picture.  As you can see there is a lot of sunlight coming in the window, but there were no mirrors this low to the ground that could have created a reflection.  After looking at the picture further, I believe it is something more.
The reason I feel concerned is that here in Gettysburg there are a lot of companies that do ghost tours--so many, that I am afraid they are overshadowing the sanctity of this hallowed ground.  There are a couple of companies in town that I think do a quality tour and have a respect for those in the afterlife, but then again there are those who stand outside "hawking" their tours.  And, then some of the things you hear them say about spirits sound unbelieveable.  And, it seems like every time you turn around there is another shop opening up advertising their spooky tours and paranormal items.  I truely hope this element doesn't completely take over the town for the story of the battle that was the turning point of the Civil War and those who fought in it and the civilians of this town is so much more important for every American to know about.
