Believe it or not, there is a small band of endurance horses
from Idaho
that carry this "genetic trait". Colts express "horns" more
often than
fillies. Most have no chestnuts. These are short-coupled
small horses
with one less lumbar vertebrae than Arabians and two less
than THB, STB,
QTR,etc. And yes, they are lucky.

So it seems that one Moyle is still involved with horses,
but is now a veterinarian!
