Abstract
A convertible public exhibition facility includes a stadium having an exhibition area and a seating area that is situated about the exhibition area for permitting spectators to view activities taking place in the exhibition area. The exhibition facility further includes a movable natural grass activity platform that has a surface area of natural grass that is at least 10,000 square feet and that is constructed so as to have a characteristic frequency of at least 6 Hz. Situated within the natural grass activity platform is a transport mechanism that is constructed and arranged so as to be able to move the natural grass activity platform as a complete unit from a location that is outside of the stadium to a location that is within the exhibition area. Preferably, the location that is outside of the stadium is an outdoor location that provides optimal conditions for the growth of natural grass.
