Charles Becomes a Drive-In River

An amphibious car rolled the viscous surface of the Charles last Sunday, but it aroused the interest of few people besides a policeman who threatened to arrest its driver for disturbing the peace.

The driver--Man M. Bernstein, 34, a teacher in a Boston private school--said yesterday that he had taken his 1964 Amphicar "for a Sunday drive" between Watertown and Cambridge, "I'm always in the Charles," he said.

"Either people resent the car and think it's immoral or else it inspires them to dream," Bernstein mused. He admitted, however, that "it's actually not really a very good car or a very good boat."
