Abstract: Features for assembling a physical boundary are disclosed. The boundary may be used in a variety of physical activities, including a pit for Ga-Ga ball. The boundary is made up of panels that can be stowed for transportation and then deployed to form the boundary. The panels are coupled together and secured to the ground using posts. The posts can secure directly to the ground or to supports. The panels may include a variety of features, including windows, ports, pockets, stiffeners, tensioners, and entry ways. An access such as a zipper in the panels may be opened and closed to provide an entry way. The panels and posts can be stored in a portable kit and deployed in a place of interest, such as a park. The assembly can then be broken down, stored as a portable kit, and transported. Associated methods of assembling and use are also disclosed.
