Oh, I'm actually surprised to read your statements. Especially as you got the pack at maybe 50% of my cost. The only thing we have in common is not being deeply into the horse culture. Although I never cared much about horses, I love tending to them in my game. This pack is - along with Cottage Lifestyle(?) probably those adding most to my game in general. And I like that we can add the horses to any world and create the western or modern style environment that we want.
Do you have other worlds? Did you try building a ultra-modern stable in San Myshuno or Newcrest?
The only thing that I miss at times is to compete for those equestrian awards in other worlds than Chestnut Ridge. It just feels a bit weird traveling that far to participate. It would make sense if equestrian sports was a thing in other worlds, too, if we wanted to add the feature there.
I agree the b/b catalog is mainly relevant to Chestnut Springs, but at least the nectar making items are used all over my game. Some rustic furniture are good in many countryside worlds, too. Especially when there is a version without the native patterns.
