Concerts, parties, and other entertainment were added and it earned $3–4 million in revenue for the city every year. Following a "mini-riot" in 1989 at an off-campus apartment during Poly Royal, the events in 1990 would cancel the event "indefinitely." Two nights of rioting on April 28–29 led to 127 arrests, over 100 injuries and 14 police injuries on top of "several hundred thousand dollars'" worth of damage. A liquor store near campus, Campus Bottle, was destroyed by revelers demanding alcohol. The second night was much larger than the first as people were leaving a concert on campus and parties off-campus were broken up and revelers flooded the streets. Mayor Dunin called the events "the worst experience in the history of San Luis Obispo." After a meeting between Mayor Dunin and University President Warren Baker the following Monday, Poly Royal was canceled from that point forward. The name Poly Royal returned in 2001 as "Open House Presents Poly Royal", a scaled-down version that was designed for students and parents. Another "mini riot" took place in the same neighborhood, across from Campus Bottle, in the early morning hours of March 7, 2015. Over 1,500 young adults converged on the area to celebrate "St. Fratty's Day." Several dozen students climbed onto the roof of a garage and the building collapsed. San Luis Obispo has been home of several other events, including a stop on the way of the Olympic Flame Relay, the Tour of California bicycle race, Cinco de Mayo celebrations, and a long-standing Christmas Parade. In May, the Madonna Hotel hosts the annual California Festival of Beers, which includes beer tasting of over 200 craft beers. Another attraction is the development of Edna Valley into a well-known wine region. Just south of the city, people can spend an afternoon wine tasting several wineries in the area with a very short drive. The wine region extends north beyond Paso Robles (30 miles north) and south to Santa Ynez (70 miles south). During summer months, a free outdoor concert Friday evening is called Concerts in the Plaza. Other noteworthy events include the San Luis Obispo International Film Festival, Festival Mozaic, a classical and crossover music festival, and the Plein Air Festival. San Luis Obispo hosts a farmers' market where vendors sell food and goods and various visual and music artists perform. Since June 2000, the first Thursday of every month is The Bike Happening (also known as Bike Nite) in San Luis Obispo.
