The symposium and the conference at Duke University dealt with weather modification, because those of us in the National Conference of Lawyers and Scientists of the American Bar Association and the American Association for the Advancement of Science believed that it was essentially a noncontroversial topic. The governor of Washington was having the militia sharpen their bayonets to do battle with the Idaho militia over claims that weather modification in Washington would rob Idaho of rain. Thus, the author approaches this symposium with no little trepidation but have learned that scientists and lawyers with interests in weather modification are characterized by good manners. Not only are there differences in attitudes about cloud seeding, but also there are legal differences among the 31 states that have enacted laws dealing with weather modification.
