Today there will be 420 festivals to celebrate National Weed Day. It started in the fall of 1971 because the Waldos planned to meet at a statue of Louis Pasteur at a high school in San Rafael, Calif. at 4:20. They went on an expedition to score some free weed from a plot of marijuana plants abandoned by a Coast Guard service member.
The Waldos kept meeting up at 4:20 to find the plot, but even after they were unsuccessful, the group used 420 as code for their pot-related activities, such as asking others if they had any marijuana or if they wanted to smoke some.
