Bill - Actually, I had forgotten about this serious use of the ole
horn!  Probably because I have grown older and find myself just smiling
& waving at folks who blast me with their horns?  You are right, though,
in that your's seems to be the premier reason to have an especially loud
horn!

I still find that the use of my horn is mostly utilized in trying to get
dumb animals out of the road before I run over them.  Remember, I am a
veterinarian, so, when I run over some genetically-deficient animal
(including some of the upright-walking mammals), I do have a reputation
to protect & it usually involves hours of arranging for intensive care,
etc.

I'll willingly admit, though, that those nifty horns which play the
abbreviated version of "DIXIE" still prompt me to hurriedly pull over to
the kerb, jump out of the ole Vanagon and snap to attention with a
delightful salute!  ANYTHING that still upsets our left-wing,
draft-dodging, anti-American-protesting, hippy-pinko-commie-fag liberal
faction of  our American brothers STILL warms my heart, greatly!.
