This year you will not have time to participate in the flash mob, which will be discussed, but the 2018 year - at your service! "In the subway without pants" - an annual event, held in January (the exact date is announced a month before) in the form of flash mob. During this, people ride the subway without wearing pants and skirts, and at the same time try to behave naturally. The event is organized by the art group Improv Everywhere.
