The big indoor arena has panels on the two unwalled sides which allows a breeze to blow though when it is hot and shelter from the elements when it is cold. During the hottest and coldest times of the year, a round corral will be located inside.
It has outside pens, then an alley all around, surrounding the inner round corral. The alleyway connects this area with the indoor arena. There is a large corral where the horses can be released when they are gentle enough to catch easily so that they can stretch their legs.
