Random House Dictionary:
"...activity requiring skill, often of a competitive nature"; "particular form
of this, especially out of doors"; "diversion, recreation, pastime". Ergo,
soaring = sport. No question about it. And a great one it is. Yesterday,
early october, 11500 ft over the San Gabriel Mountains of Southern California,
2 hours. Last week, same place, 13800 ft., 3 hrs.
