ABSTRACT:
A playground golf course with an artificial turf, the greens of which are formed by disposing a thin resilient urethane foam layer below the artificial turf so as to reduce golf ball bounce and hence roll on the artificial turf. Greens are formed by disposing a polyethylene buffer below the thin layer and disposing a green boundary edge member composed of an artificial turf belt member around the artificial turf. Greens are also formed by tensioning predetermined portions in the vicinity of the periphery of the artificial turf with springs. The playground golf course is formed by disposing a plurality of greens formed in such a manner in an existing athletic facility. The playground golf course is composed of the greens, a golf club with two club heads formed at both ends of a shaft, a golf ball with reduced flight characteristics, and a golf tee that allows players to easily hit golf balls.
