I was just talking to Anderson Feed and they said we can now get Stabul 1 at Tractor Supply.  It's a special order item and requires a 10 bag order, but it definitely is now available.  Just have to talk to the store manager and if they're hesitant, they can call Anderson Feed to set up delivery.  Probably a good idea to get the free sample of Stabul 1 from Anderson Feed just to be sure the horse likes it.
