Curb Cocks?

At Barnes & Noble this afternoon in a futile search for a rental cost book I
came across an architectural dictionary, courtesy McGraw Hill Publishing, a
bit too expensive for this day, but it had some interesting words & phrases
in it.

Now, I've heard of a curb warranty... THE BIG SIDEWALK QUESTION -- is there
anyone that you know of that collects historic curb cocks?

I imagine there are different impressions available and that the depth of
plumbing varies dependent upon climactic frost action. Do curb cocks ever get
full up and freeze over? Are curb cocks shorter in the South? Has anyone here
got a used curb cock extender?

Does a curb cock last longer than a curb warranty? Can you adjust them if
they cease up? What happens if your arm is too big and it gets stuck?

What happens when a really big ass truck drives over a structurally defective
curb cock?

Can you get an acid resistant curb cock?

Thanks,
