No, I would be COMPLETELY stressed out all of the time. Even when we go on vacation, and I know they are being well cared for I am constantly thinking about them.
I also would rather spend the money on taking lessons, instead of spending it on board for a horse I would rarely see.
But, I guess if you have the money, and could find someone to ride the horse when your gone to keep it active and happy it would work. I guess it's just what you want to do. Starting with one horse would probably be the best option though.
