The parking lot between the arena and the warmup jumps will be available for shade tents and one vehicle at no charge.
There are beeeaaauuuutiful, 12 X 12 box stalls indoors that will be available for rent for the weekend. In another room are less fancy but still clean, private and 10 X 10, these stalls are perfect too. This area will be locked when the event is not running.
And a middle option: there are outdoor box stalls, 10 x 10 covered with a fabric roof that will be available for a modest fee. No ability to lock up unfortunately. These stalls are located around the side of the arena and at this time we are not sure if there's a convenient door to enter the arena on that side (we suspect you'd have walk around to the lobby or the rollup doors on the shade tent side).
