Manhole Covers, Part 2

IMAG0052A couple of years ago I wrote up “Why is a manhole cover round?” and got a few good comments on it. Now that I live in London, I see how American that question really is.

Notice these two that I saw when walking through Wandsworth the other day. I still think a round cover is the better option, but is it really worth anyone’s time to think about it this much? (please don’t answer that)
