The way the world works is this: land will be used in the end for the greater good. Of course our idea of what constitutes the greater good is the horses. But for the majority of people it's no horses, and the philosophy is that although there were farms and horses before, times have changed, and now the majority of people don't like the horses and therefore the horses must go. I've seen this happen again and again, and been told flat out that's how most people feel: that was then, this is now, and it's time for the horses (cows/dogs/chickens, whatever) to go elsewhere.
I know a woman who has a boarding kennel, properly licensed and inspected. It's been there for probably 20 years, maybe longer, and the place has been a farm since the 1700's, with a 1700s house she lives in. The zoning where she lives has changed since she's been there - she couldn't get a kennel license today, but no matter, she's grandfathered in. Adjoining land has been sold over the years and there are now houses nearby. Of course her farm (horses, sheep, chickens) and boarding kennel have been there since before these houses were built, but the people who live in them now have complained to the township because they now live near a boarding kennel and they don't like it. Guess who lost? The township has agreed that her properly licensed facility, grandfathered in, must be shut down. Why? Because she's one household saying YEA while there are 5 households saying NAY. Majority rules, the neighborhood has changed and the boarding kennel is no longer acceptable to the new people.
