On Friday, April 20th, thousands of people descended upon Porter Meadow at UC Santa Cruz for Four Twenty (420), a counterculture holiday observed in cities throughout the world, where people gather to celebrate and consume cannabis.

Cannabis is recognized as medicine by the state of California, 17 other states in the USA, Washington DC, and a growing number of people and governments all over the world.

Four Twenty in Porter Meadow at UCSC is an unorganized annual tradition. Last year, rain caused people to seek shelter under the forest canopy. This year, it was the hot sun which drove people to the shade provided by the trees.
