Where in Duluth?

The switch for the hood at Jims's Hamburgers.

Nope.

Sparkhawk has his followers. Charlie Parr has his aficionados. Trampled by Turtles has their cult. This picture is MY fan...

+1 TK.

That is the fan switch for the R.T. Quinlan's phone booth.  Thankyouverymuch!

But hasn't that phone booth also been used as a restroom?

Jimmy's got it. Damn you!

Two guesses for someone to correctly identify a switch? 

I'm amazed.

So am I. I actually thought this would prove to be too difficult.
