I read thru these every so often, noticing how at these auctions these "baby horses" will be asked to run faster than they will ever run in their entire lives. 

This is how we SELL baby horses to new owners.  Gotta wonder what making them do these kind of drills does to their baby musculoskeletal system........all it takes is once, IMHO
