Did I see today where they shut it down again?

The "season" itself ended, so technically the track didn't close down from the amount of horses that died (which is now at 30 or 32 depending on what article you read). The Breeder's Cup is slated to run at Santa Anita in November, so we shall see what happens next. Here's a few recent articles.

I still don't think they did the "right" thing by banning Lasix (that would be like banning an asthmatic from using their inhaler), however I did read an article that discussed only banning it in 2 year olds starting in 2020, so the 3 year olds (Triple Crown runners, etc.) would still be able to use it. Makes me wonder if they're trying to get away from running horses as 2 year olds...?

I didn't read the article, just saw the headline that also included a trainer being banned.   I should have paid more attention!
