Then that is good news, although it is not fair to allow some Hawthorne horses to run and others not to, probably based on connections.
Might have had to jump through some outside quarantine hoops. I can't see them just saying, "You're Mike Stidham, come on down!" after a few of his horses came up surprise positive when he was trying to ship out.
Is there any indication in the pp's that the horse was working out anywhere between the time Stidham left here with the sealed trailer and now?
