(FORTUNE Magazine) – The Jackson, Wyoming, Boy Scouts are doing their bit to turn last year's trade deficit with South Korea into a surplus. Their export: hundreds of antlers shed by elk in the Tetons during the winter months and gathered by 300 Scouts and Cubs of local troops in spring after the snow melts. Since 1968 the troops have auctioned their harvest, raising $1.2 million. The big buyers: mostly South Korean businessmen, usually acting through U.S. representatives. The antlers are ground into powder and sold in Asia as an aphrodisiac. This year's auction raised $76,177.75. Of that, about $60,000 will go to capital investment, namely buying alfalfa hay to feed the elk in their habitat. The U.S. Treasury will get about $4,000. The Scouts keep the rest. Jim Griffin, assistant manager for the U.S. Fish and Wildlife Service's installation in Jackson, estimates that South Korean buyers spent more than $30,000 this year. That's less than usual, but even so the Scouts will be adding 0.023% to the $132.2 million trade surplus that the U.S. has racked up with South Korea in the first three months of this year. In 1990 the U.S. had a $4.5 billion trade goods deficit with that country. Do the boys ever experiment with their product? Not to the knowledge of Scoutmaster Vic Lindeburg, 45, an auto mechanic. But, he jokes, ''we talk about gnawing on these things behind closed doors when we get older.''
