well, I might as well tell you about "my stable"
So, things are a little bit different around here, we have stable communities, where there are many owners. Sometimes they own maybe a house for 30 horses, maybe you just own a stall or two.
I board in Víðidalur, where the "horse club" Fákur is located. If you are a member of that club you have access to an arena, 2 large pens (I think there are two, might be more), and many round pens. There are also alot of trailes there, some witch lead up to other stable communities. There are two (again, I think there are two) what we call skeiðvöllur, its an oval track, one side is often longer and straight. And finally there is an animal hospital there.
In the house that my trainers family owns there are stalls for 8 horses I think, a tack room, a "hay room" and a coffe room. Also a pen outside to let the horses out in.
I found a map :)
The large house in the middle is the arena ! Everyhouse with a red roof (on the map) has something to do with horses !
I just counted and there are 70 houses that keep horses
