Funny,
Just ran across the below article about Gulfstream doing Milkshake tests on every Graded Stakes entry. I remember reading that Mullins requested stall space at Hallandale and then backed out of the deal. Coincidence?:

Lots of Gulfstream Trainers have horses who have suddenly started coughing.
They probably will have to wait until their respective springs meets.
