is the NSA in your neighborhood?

While writing a few articles last night, I had run into internet issues. So as any webmaster would I quickly reset my internet connection and went to re connect. What I saw next threw me for a loop. I have heard of the NSA, better know as the National Security Alliance, but I had never actually seen anything proving their existence, or at least not here in Illinois. As I was searching for my connection I came across " NSA Surveillance Van #3. It kind of shocked me and left me a bit uneasy. What do you guys think of this?
