It's always fun to see organizational chaos. Ray Scott, man behind the bass-fishing for money phenomenon, wants teh 270,000 members of his Bass Anglers Sportsman Society to stay out of Cuba.

"American Sportsfishermen and tourists are being lured to Cuba to help bolster Fidel Castro's crumbling economy and, in effect, buy bullets which will be used to further the escalation of Communism," Scott writes in the lastest newsletter from B.A.S.S.

"There's no sense in compromising our principles of democracy by traveling to a Communist country just to catch a few fish," he adds. "freedom is worth a lot more than a stringer of bass."

Meanwhile the Bass Research Federation, which Scott founded and for which he still serves as a director, chief fundraiser and big contributor, is busy sending people to Cuba to check out bass fishing.

BRF sent Dr. Thomas L. Wellborn Jr. and Dr. Roy C. Heidinger, who were invited, it says in the BRF newsletter, by the Cuban government.

BRF wrote that the two scientists ahd no doubt, after the trip, "that with proper management these three lakes (Hanabanilla, Zaza and Treasure) have the potential of producing some of the finest bass fishing available." It added that the pair found the Cubans "were friendly and seemed to have a great desire for technical knowledge on how to manage these lakes for bass fishing."
