30years ago I would have 4 maybe 5 hounds. Turn 2 loose at a time .. no beepers no trackers lucky to get a race at all. There was very little game. But man when it did it sounded like the devil was coming after your ass! 2 dogs would sound like 20. Wasn't no switching off ,or no loosing either . what u jumped was what u jumped and didn't loose it. Pray like hell that you would either kill or get your dogs back soon. Lol. 1 out of 7 maybe if u was lucky on both. Lol. The **** came off of a Shaw dog that was out of Illinois. That's all I know and that ain't much.
