Horse likely raced with before and is equipped with the bar again .

Helps support of healing quarter cracks .
Years back this was a bad bet but today the bar shoe is modified
and lighter than the former Bar .

Drosselmeyer won the BC with Bars .It was used to protect his tender
frogs .Then again Mott has the best farriers so I trust the change but
every case is individual .

It means that Noble Moon is in a race.
If this horse ever runs in a race without a bar shoe(s) on bet the house on him.
Talented colt....no foot.
