What the heck is this thing ?
Ok , firstly , I admit , these pics have been in my camera a while. This thing just apeared one day at this corner , I don't know what it is , but it has the city of ottawa logo on it. A day or two later, it was moved to the opposite side of the intersection , and a few days later it was gone.

I'm guessing ... traffic counter ?
Who knows. That dish at the top looks like a really tiny radar dish. And it's pointed at the center of the intersection.

The weirdest things these days keep popping up.
