So cool, thank you!

Soooo the Astronomicon?

And also a nested acronym

Awesome, not what I expected, thanks!

It's on that little red sign, the image is just so compressed it's impossible to read

On the blurry little sign in front of it. I didn't take a photo, just noted the address and looked it up on Google Maps, so it's illegible here, but you can read it if you pull up the address and zoom.

The little red sign on the fence says "Critical Area - Keep Out". It's not very clear in the screenshot, but you can see it on streetview; the coordinates are 35.033706, -81.925449 ; it's labelled "US Government - FAA building".

I was thinking a giant laser on a swivel to shoot at the sky. But realistically, I figured it just housed power equipment or something.

50ft seems a pretty pathetic increase in range. They should have made the effort to make it pointy instead.
