Where in Duluth?

Near the entrance to the Bat Cave.

I do believe that's at Target. It probably wouldn't have clicked in my mind so quickly if you had posted the photo in black and white.

Actually, no. Nice try though.

Wow, I was almost positive of that. I do believe Target has bright red phones that you can pick up to call for help. Tricky. I guess I'm stumped now.

The skywalk at Essentia?

We have a winner!

Yaaaay! I've always found them amusing for some reason.

I used one of those once because I needed assistance finding a meeting room, and got chewed out because it wasn't an emergency.  Apparently 'help' = 'emergency'.
