Bay Shore has an active nightlife, with bars and restaurants on Main Street; it is safe during busy hours. Women walking in coastal village centers generally report feeling comfortable. Isolated LIRR station parking lots warrant attention late at night. Catalytic converter theft is a frequent complaint throughout the region.
