From the Annals of the National Treasures – In 1968, Lady Bird Johnson dedicated Padre Island National Seashore. Padre Island is the largest barrier island in the U.S. and PINS is the longest seashore in the national park system. Protecting this precious resource was not easy. Texas attempted to establish a state park on Padre Island beginning in 1936. The effort failed in a contentious struggle between public and private interests over ownership of the land. In 1958, Sen. Ralph Yarborough (D-Texas) introduced a bill to establish a national park on the island, and the proposal was finally signed into law in 1962. The dedication of the park followed five years of condemnation proceedings.
