The next important entry on Jastremski's schedule is this week's Santa Clara ( Calif.) International meet. He also plans to take his family on a motoring trip through the Western U.S., but that will be, he pointedly says, "after the Olympics." Should he fail to make the team he would return to the U.S. Military Academy for his last few weeks of Army duty. But never mind that. When Jastremski recently advised a friend, "You can reach me at West Point in August," it did not mean he had suddenly lost faith. By chance, the U.S. swimming team will be training at West Point before it leaves for Munich.
