Handball---
Most people these days associate the term with Soccer. But not so long ago, many people played American Handball.
American handball, known as handball in the United States, is a sport in which players use their hands to hit a small rubber ball against a wall such that their opponent cannot do the same without the ball touching the ground twice. The three versions are four-wall, three-wall and one-wall. Each version can be played either by two players (singles), three players (cutthroat) or four players (doubles), but in official tournaments, singles and doubles are the only versions played.
Constructed in 1902, Golden Gate Park has handball courts that used to be heavily used. Today, they sit quietly, largely unused, but available without reservations.
Perhaps you can hear the "thump" of the balls hitting the walls from the past, and the crack of balls on bats next door at the Big Rec Baseball Diamonds.
