I have "horsey" cousins who train them, compete in rodeos, etc. Food is hay, mostly, comes in 50 lb bales that have to be trucked home, unloaded, divided and rationed. But that's just the start. The horses have to be exercised daily, groomed, loaded into trailers to go to the vet or farrier if he doesn't come to you, that means a truck to pull the trailer. And there's the tack to keep in order, the stalls have to be cleaned constantly because standing in wet dirty bedding hurts their hooves. Horse carts replacing the truck means a lot of other changes. It works for the Amish because it is all integral to their lifestyle. So the relatives love it but it makes me tired just to watch. :)
