Golf

Golf is an outdoor Earth game that has been enjoyed by Humans for several centuries. The object of the game is to sink a ball into a series of holes, using special clubs to drive the ball towards the holes in the least number of strokes. During the late 2370s, The Doctor took up the hobby in effort to follow up on the tradition. Starfleet officer Reginald Barclay also had an affinity for the game.

In 2377, The Doctor canceled his holodeck "tee time" at Saint Andrews so that Tom Paris and B'Elanna Torres could spend three hours together on Gedi Prime. 

During a visit aboard the USS Voyager by a holographic Reginald Barclay, The Doctor requested that they might perhaps play nine holes either on the "back nine" on Gedi Prime or Pebble Beach at sunset. Barclay, however, attempted to avoid The Doctor's tee time by having Seven of Nine teach him kadis-kot. 

In an alternate timeline, in 2404, Commander Reginald Barclay saw The Doctor at Starfleet Headquarters and thought he had missed their golf game.
