Picnic Day
Take part in Picnic Day. If you want to experience the single largest student-run event in the United States, visit Davis in late April and revel in Picnic Day. The day consists of over 150 free events, most of which take part on campus, including dog races, food tastings, exotic animal shows, an infamous Battle of the Bands, an exciting fashion show displaying unique student work and much much more. As one might expect, a good amount of drinking takes place throughout the day and by late afternoon there tends to be intoxicated people everywhere, but the mood of the event is very positive and arrests are very few relative to the number of the 50,000+ attendees.
Whole Earth Festival
Experience the Whole Earth Festival (http://wef.ucdavis.edu/). Whole Earth is an annual celebration of counterculture, art, politics, sustainability, and music, taking place over a three day period on Mother's Day Weekend. Tens of thousands of hippies, punks, and miscellaneous weirdos descend on Davis for this event, taking place on the UC Davis quad.
