Who hasn’t enjoyed tossing a Frisbee with a friend? How about throwing that Frisbee around the fields, along wooded trails and across streams of Central Pennsylvania? That’s exactly what the sport of disc golf offers. The popular pastime combines the precision skills of tossing a Frisbee with the fun and challenge of a golf course. The goal, like that of golf, is to sink your disc into the “hole’’ or chain metal basket in as few “strokes’’ or throws as possible. Valley View Park in Altoona features one of the region’s first disc golf courses, and park manager Ron Tragon reports that a growing number of players are taking advantage of the local facility throughout the spring, summer and fall seasons. The Professional Disc Golf Association, based in Georgia, is the governing body of the sport that’s been gaining steam since the 1970s. The PDGA invites top players to compete around the United States and the globe.
