I believe Gun Runner (and other Assmussen's) flew out last week on Tuesday (18th) so he will have two works over the track (worked Sun 23rd plus one more next week)

Frosted and Happy and the Mott's flew out last Sunday (23rd)

Effinex, sadly, still not there yet - flies out today:

Effinex ‘holding his form' for Breeders' Cup Classic
By David Grening
Effinex and Jerkens’s other Classic contender, Shaman Ghost, are scheduled to ship to Santa Anita on Wednesday (26th). Jerkens said both horses will have one work at Santa Anita, though he isn’t looking to do much with Effinex, who just finished second in the Jockey Club Gold Cup on Oct. 8.

Brown's/TAP's all still back east too - imagine some may go on flight today but don't have that definite.

By The Moon, by the by, has been there since early Oct.
