These days, a lot of people know that April 20th – 420 – is a day people celebrate cannabis. Less well-known in the calendar of drug-related holidays is the day before, April 19th. It’s known as Bicycle Day, and it started as a quiet, subversive celebration of LSD. Now, Bicycle Day is celebrated around the world.
