Seventy-five miles south of Chicago there is a whistle-stop called Shipmont. (No ship has ever been anywhere near it; neither has a mountain.) It lives because of a small college; the college, in turn, owes its maintenance to an installation of great interest to the Atomic Energy Commission.
Shipmont is served by two trains a day -- which stop only when there is a passenger to get on or off, which isn't often. These passengers, generally speaking, are oddballs carrying attache cases or eager young men carrying miniature slide rules.
