Bob Riley of Springfield, who directs the area junior golf program, had to hurry 20 players off the course recently when an electric storm descended on Woodmont Country Club in Rockville during the Gorin tournament. During the same storm in Fairfax County, a golfer was killed by lightning at the Greendale course in Franconia.

Lightning on a golf course is a serious matter. Riley suggests: "Try to take cover in a building or shelters that are on most golf courses. Throw your clubs down if you have to, and remove your spiked shoes. Don't stand under an umbrella because some have metal shafts and metal webbing. And I think this is pretty important: you should try to avoid isolated trees. Dense woods aren't so bad. Hilltops and open spaces are bad."

Darren Veitch, ex-Washington Capitals hockey player whose slap shots on the golf course sometimes travel 300 yards, is scheduled to join former teammate Dave Christian, Washington Bullets Dudley Bradley and Dan Roundfield, and other athletes and media personalities Monday at Lake Arbor (near Capital Centre) in a tournament that will raise funds for the shock trauma unit at Prince George's General Hospital.

Veitch, who was traded in March to the Detroit Red Wings, still resides in Mitchellville and plays out of Prince Georges Country Club. The long hitter made three eagles in an opening- round 70 in the Maryland Open. "I've made two eagles in a round before, but never three," he said. He was in contention in the Maryland Open and also in the June Templeton Oldsmobile Open at Prince William. Veitch has twice won the Saskatchewan Amateur. Other notables expected for the benefit are Greg Ballard, Chuck Hinton, Willie Wood and Yvon Labre. For more information, contact Regina Schewe at 556-0844.

There was a member of the Bubes family everywhere you looked in recent quarterfinals of the Woodmont men's club championship. Of the eight quarterfinalists at the Rockville club, four were brothers: Alan Bubes, Mark Bubes, Kenny Bubes and Ron Bubes, who flew in from Los Angeles to compete. When it got to the semifinals, Mark defeated Kenny and 17-year-old David Colodny defeated Mark Miller.

In the final, Mark Bubes made six birdies in a scheduled 36-hole match and defeated Colodny, 4 and 2, for his fourth club championship.

Ron and Mark have squared off three times in the final, with Ron winning two of those three.

Scott Verplank, who made his professional golf debut in June at the U.S. Open on Long Island, where he finished 15th and won more than $8,000, has signed with ProServ of Washington, a career management firm. Verplank, the NCAA champion from Oklahoma State, last summer became the first amateur in 31 years to win a PGA Tour event when he won the Western Open.
