Looks Like Randy has come out of the closet and made his first HORSESHOE Caleb went down the shed I had a piece of hoof the same as in your pic but I must have chucked it out in my last big clean up not too sure about the race horse question but I would guess they would have used lighter HORSESHOES on them plus they would have been weighted BUTIDOSTANDTOBECORECTED But I never had much to do with the race horse side of HORSESHOES Going by the pictures of all the HORSESHOES in the shop they wouldnt have used any of them on a pacer or trotter B S Pete
