So I shot this while on a walk with Ellen tonight in historic Roswell, GA. I have no idea the significance behind it because I didn't take time to read the sign. I'm sure you can search it on the interweb. One thing I do know is that it is a stop on the Roswell Ghost Tour. You really should check out their website/myspace page. Great stuff. I love the news report when the lady says she photographed an orb.
