What are these things (with pictures)?

Yes, it is, with another one even closer (I couldn’t photograph that one as there was a family gathered around it; would have looked suspicious). But seriously, where do you see a 2? I didn’t see one when I was there and I can’t see it now, no matter how much I stare. If there was a 2, I assume it was on the yellow plastic stuff whose remains can be seen on the sign.

I see a 2 in the distance shot. It disappears in the close-up.
