Deer-proofing an Audi

["Horch, August" <Horch.August@tci.com>]

Coming home from Fort Collins on Friday night, enjoying some spirited
driving on one of the few twisty roads in Colorado, I came up over a
hill doing about 60 & find a poor Doe standing right in the middle of
the road.  I hit the brakes and dove for the ditch.  The doe, of course,
ran straight for the car; I hit the doe & the ditch at about the same
time.  I'll save you the gorry details, but there isnt' much left of
Audi or deer (altho the Audi made it home afterwards...)  :-(  Anyone
out there with experience with those deer whistle's I've seen?  Do they
really work?  Any favorite brands?  I really don't want to be
responsible for the loss of anymore animal life.  Many thanks.
