Abstract: A mounting device supports an elongated linearly extending member at its bottom end vertically in the ground. A length of chain has a bottom end coupled to the mounting device and a spaced opposite top end coupled to the member in the area of the top end of the member in a manner whereby the chain extends parallel with the member in spaced relation therewith. A tension adjusting device is coupled in the chain intermediate the ends in a manner whereby the chain functions as an adjustable strut to maintain the member in vertical position. A net supporting device supports a net in the area of the top end of the member and perpendicularly to the member, and includes a roller rotatably mounted on the member closely adjacent the top end thereof. A length of cord passes around part of the roller in a manner whereby a first part of the cord extends in spaced parallel relation with the member between the member and the chain and a second part of the cord extends perpendicularly with the member for supporting a net.
