Bocce

So what are all those people doing standing there? They're playing what I call "poor man's golf" or "an activity for all ages to enjoy out on the lawn on a neither cold nor hot afternoon", in short Bocce Ball. 

 One person throws a small white ball, called a boccino, out on the lawn somewhere. Then everyone else takes turns throwing a colored wooden ball toward the boccino. Whichever ball lands closest to it gets a point for that team.

 In addition, any colored balls from that person's teammates, which have landed closer to the boccino than any ball from the opposing team also earn a point. If someone else's ball hits your perfectly placed one and knocks it away into neighboring yards, too bad.

Since each round must be played from the spot where the boccino rested last, each new throw causes the players to migrate.

It's a pleasant game for a warm evening...but I wouldn't rely on it for exercise.
