I walk into the room with the red brick wall and checkered mat, and the pyramid is already growing. Mel Costa and Renato Colossos have been building up to this pony play fantasy for weeks. One rider climbs onto the human pony, then another, then more, men and women piling up in a stack of bodies and heavy weight, laughing and cheering. How much can one pony carry? Unbelievably much. It's hard, intense, almost too much, and the ponies love every extra rider. In between, the heat rises. Strong group pony play. Saddle up.
