I guess I still don't understand the significance of the 42, but I sure like how you seem to find them all over town.
42 is The Answer! lol : http://hitchhikers.wikia.com/wiki/42
The meaning of 42 escapes me too. I'll have to click the link you left for Elizabeth.Darla
It's the Answer to the Ultimate Question of Life, the Universe and Everything from _The Hitchhiker's Guide to the Galaxy_, a novel by Douglas Adams. I see pop culture references to it quite often, most recently in Doctor Who and in The Big Bang Theory, but I don't see the 42 as public art in any other cities. Of course, I don't get out much ;)
