A sporting field measurement system is disclosed wherein a user is prompted to select, on a mobile device, a field for marking from various sporting field types including, but not limited to football, baseball, softball, soccer, lacrosse, track, tennis, basketball, cricket, polo, rugby, Australian football, volleyball, and badminton. The Global National Satellite System (GNSS) or at least the global positioning system (GPS) is used to locate a user's device. An application displays, on a display, of the mobile device, the dimensions of the specified sporting field as an overlay on a map, generated by the positioning system and it will communicate with the GNSS or GPS of the device to allow the user to track his or her movement along a specified path of a proposed field. This will allow the user to place the appropriate markers and/or paint the field. Deviations from the path may be indicated on the display of the mobile device or by an audio indication generated by the mobile device.

A movable dasher board system optimizes user safety in a hockey rink or similar arena. A bottom structure, provided by a sliding bottom surface or roller assembly, has low friction characteristics, typically a .sub.s of 0.05 or less with respect to ice if a sliding surface, or if roller bearings an effective coefficient of rolling friction 0.04 or less. A dasher board assembly is operatively connected to and extends upwardly from the bottom structure. Biasing and impact force absorbing devices (such as pneumatic or hydraulic or spring-encasing telescoping tubes, or foam, gel, or compression springs) bias the bottom structure and dasher board assembly to a desired position and absorb the impact of a human hitting the dasher board assembly to minimize the possibility of injury to the human. The system may be installed in a pre-existing rink or other arena.

Embodiments described herein relate to a system which includes a vertical support, a elevation coupler attachable to the vertical support, and a first outer horizontal member couplable to the elevation coupler to extend from the elevation coupler at an angle substantially perpendicular to the vertical support. The system includes a first inner horizontal member couplable to the first outer horizontal member. The system includes a second outer horizontal member couplable to the elevation coupler and a second inner horizontal member couplable to the second outer horizontal member to form a grid in an elevated position to provide an arrangement suitable for a game. The vertical support is adjustable in length to adjust a height of the grid.

An anchor includes a frame assembly and a removable cover plug. The frame assembly includes an access frame having a bottom and a wall defining an upper opening and a cavity therein, a first flexible seal extends above the upper opening of the wall, and at least one vertical member is in communication with the cavity of the access frame. The plug is operable for covering opening in the access frame. The plug includes a platform for supporting synthetic turf on the platform. When the plug is removed, at least one stanchion of a base, a home plate, a double base, or a pitcher's rubber is engageable with the vertical member.

A method of assembling a portable fenced-in ball playing area that includes a plurality of panels that have an upward slot on one end of the panel and a downward slot at the other end of the panel. The panels are assembled into a polygon shaped pit, such as for a Ga-ga pit, by fitment of upward and downward slots on adjacent panels. No tools are necessary for assembly. The panels can include hand holes for easy carrying. Some panels may have a top indentation or recess to assist children in entering or leaving the fenced-in ball playing area, such as a Ga-ga pit. These panels can be reversed so that the recess is facing downward to form a goal opening for a game using a ball, puck or the like.
