What does LSD have to do with Bicycle Day?

LSD (better known as acid) was created in 1938 by Swiss chemist Dr. Albert Hofmann

LSD was discovered accidentally after its inventor touched his face and hallucinated

Unlike many drugs, the first time a human ever tripped on acid was recorded first-hand by a scientist. Swiss chemist Albert Hofmann, curious about the "not unpleasant intoxicated-like condition" that overcame him after an accidental exposure, set up a rigorous experiment to test the drug's effects on himself.
