I,m not pulling anyones leg here and frankly I,ve never heard of this but it was given to me by a Farrier so I,ll let loose and cop the ridicule if any.
He was talking about mud runners.
He always bets a mud runner with large hoofs..
Now I,ve heard of thinking outside the square a number of times.
The problem with us poor sods is that we,re not Farriers.
