Two shots!  That's a hoot!  My mum would blow a ref whistle out the back
window when it was time to come in.  That was in suburban Los Angeles in
the late 70s and early 80s and could be heard within a two block radius.
Out in Happy Camp, in BigFoot country, two shots probably carried a lot
further.  No mention of what caliber the family homing beacon was loaded
with. Pity.  I'm just left wondering how far a  lonesome tractor steam
whistle can travel in most parts.
