Okay Baby Boomers. If you only indulge in cannabis once a year, this is your day!! Allegedly started by some highs school-age Boomers in San Rafael around 1971, 420 was code for smoking at their usual 4:20 PM time. Or something like that. Nowdays there’s a celebration on “Hippie Hill” in Golden Gate Park.
If cannabis is not your thing, then raise a toast to you fellow Boomers to show that you’re really hip.
