normally pup/yearling and veterans are ran over 150 yards now my question is this: if your scratch races are over say 165yards or 175 yards shud the pup/yearling/veteran scratch b allowed to race in the supreme scratch. ( they have only ran 150 yds) i ask becoz we might @ our own open put pup/yearling/veteran scratch on but our adult scratch will b over either 165yds or 175yds.
