Interesting fact.

I was watching the DVDs Redmare got me for Xmas (awesome!!)
Miniature Horse clinic from 2010.
Got to the section on hooves.
EVERYONE from the farrier and yes even the audience called it the Coronary band and the only time coronet band or coronet was mentioned was when the editor of the video provided CC when the volume of the person talking was hard to hear. Even though it was quite clear they said coronary, they typed coronet.
I would not have noticed except for this thread.
