At every corner....

I found myself in a couple of places where normally I would be like, Oooh, where's my camera? On this and the "egg yolk dripping out of the carton in the supermarket" inceident, I just patted my pocket and hey presto, there it is.

PS. Must apologise to Jens and Ross for leaving comments, but I uploaded this picture to the wrong day so I believe the comments will get wiped when I shift it. To respond to said comments, I think it is rust, but I'm not going to get much closer to find out.
