Ghosts of WBKR: Who Is This Ell-Bee?

So, you've seen some mysterious goings-on late at night here at WBKR, but what about what is going on outside the building? I present Exhibit A, this board with the name, place (?) "Ell-Bee" carved into it.

First off, this corner of the building has been traditionally a smoking area. I don't smoke anymore, but if the weather's nice, I'll step outside with my e-cigarette. This board showed up in the smoking area I think sometime last year. The crazy part, I have no earthly idea where or whom it came from. It's just there, propped up against the building.

Now let's talk about the carvings. Freaky! I'm guessing a sharp object, such as a knife, was used, possibly a big knife. And "Bee"? Well we are W Bee K R. I'm stretching it, but it's one thought that comes to mind. "Ell"? I don't know what the ell it means. I've also had this theory that maybe this board washed up in the parking lot (don't laugh!) after a torrential rain storm. I don't think this a part of the building that broke off one day, again, maybe in a storm, but I can't be sure. Edward Albee? Nah!

I'm going to have to do some more digging.
