Thousands pack Cal Poly concert, neighborhoods empty: See photos, video of St. Fratty’s in SLO

By Kaytlyn Leslie , Sadie Dittenber , Chloe Jones and Joan Lynch

After the annual street party took a destructive turn last year, St. Fratty’s appeared to be a much quieter affair in San Luis Obispo on Saturday, with no street parties and no major property damage.

Thousands instead turned out for an early-morning concert on Cal Poly’s campus to watch EDM groups Galantis and Zhu.

Despite students swarming the barricades around the concert venue to get in, Cal Poly spokesman Matt Lazier said there were no other major issues stemming from the Saturday event.

Meanwhile Mayor Erica Stewart lauded the city’s Police Department and law enforcement agencies that offered aid to help dissuade students from taking to the streets.

Announcer on the stage says the event will not start until it is safe and tells the crowd to stop pushing each other. Someone next to me is telling someone on the phone do not start the music yet until she gives the OK

@slotribune An estimated 6,000 students danced the morning away during Cal Poly’s “Morning on the Green” music festival — the alternative party the university organized to give students a safer option from the illegal block party that has wreaked havoc on neighborhoods and dorms in recent years.
