Hovering teleportation portals.
*shoomp* out in pasture, over the mud *zoomp* catch horse, stand on portal disk, press button *swoosh* arrive in barn aisle portal
No more trekking out across acreage, knee deep mud, lightning, blizzards, etc. to get your ponies! You can even train the smart ones to step onto the portal with a voice command, thus making it even more time efficient. Ride more than double your usual number of horses per day!
