Back when horses were transportation, they WORKED most of the day (when they weren't plowing the fields)! A modern horse that is not kept out in a pasture all the time, is spending most of their time in a stall. They have to be taken out daily for some exercise, either being ridden or trained, or at least turned out in a corral or pasture to run for a bit. If you keep the horse on your property that's not as hard to do though it does take a good chunk of time out of your day. If you keep your horse at a boarding stable, you are paying them to cleaan the stall and feed your horse every day. Less work for you, but a lot more money. My mom would ride at a boarding stable where she had a time-share on someone else's horse, That's a solution for getting to ride once a week without all the responsabilities and expense of owning a horse. And if you do own and board a horse, then you don't have to go take care of them every day.
