Somewhere in Hadley, Mass., exists what might be termed an Olympic cooperative. Here, four of the United States' top canoe and kayak prospects for the 1980 Olympic Games in Moscow live in modest means.

They provide each other with helpful hints encouraging words, and occasional massages. But most important, they keep expenses low enough so the athletes can spend more time training and traveling to necessary competitions and less time working.

"We all live together in a house, trying to make a few bucks to keep training," said Ann Turner, who lives with her brother Brent, Leslie Klein and Angus Morrison.

"It's pretty inexpensive. We make our own bread. Expenses stay pretty low. In the winter, we keep the heat turned down to zero. The atmosphere in the house is relaxing, it's encouraging."

Of the four, only Klein has never been to the Olympics. Ann Turner paddled a kayak (K-2) with Washington's Linda Dragon and Brent doubled with leading 1980 prospect Steve Kelly of New York City. Morrison will make an attempt to travel to his third Olympics in a single canoe (C-1).

The Turners will have an added incentive because their father, Howard, already has qualified for the Olympics as the team manager.

While Hadley houses a concentration of the possibilities for the 17-man Olympic team, former Olympian and 1972 Olympic Coach Charles W. Lundmark of the Washington Canoe Club considers the Washington area "the paddling mecca" of the country because "people come here from around the country to train."

The canoe club's membership lists four of the top six competitors battling for the four female Olympic spots in addition to three-time Olympian Andy Weigand.

Jacqueline Scribner, a 19 year-old from Alexandria whom 1980 Olympic Coach Andy Toro calls "the most talented young girl in the country" should join Dragon, Turner and Klein to form the Olympic squad. Should one of the group falter, Theresa Di-Marino and Nancy Leahy, both of Alexandria, are waiting to move up.

Weigand, an Arlington resident stationed with the U.S. Air Force in West Germany, remains a favorite in the C-1. Bruce Barton of Homer, Mich., a 1976 Olympian in the 1,000-meter K-2 and the K-4, has joined his brother Greg to try to return in the K-2.

Terry White of Hadley, thrust himself into the Olympic picture when he captured the 500-meter K-1 event at the recent prestigious Lake Sebago (N.Y.) Regatta.

The women, encouraged by seventh-and ninth-place finishes in last year's World Championships, would like to make some more gains at the upcoming World Games and the Olympics.

The men would like to make the final field of a kayak event for the first time. "We could make history in August. Just making the finals (in the World Games in Bled, Yugoslavia) would be a tremendous achievement," Toro said.
