4/20, an unsanctioned UC Santa Cruz event, drew in large crowds this year to the Porter meadow. With Picnic Day in UC Davis and Floatopia in UC Santa Barbara, unofficial student events are now a popular option.

What is arguably one of the largest events on campus, 4/20 comes and goes in a cloud of smoke and ash.

The weather forecast called for rain, but a crowd of hundreds descended on the Porter Meadow for this year’s 4/20 celebration.

On what was possibly the hottest day of the year thus far, an ever-growing crowd gathered at the Porter Meadow for one of UC Santa Cruz’s most infamous traditions — 4/20.
