Exploring the cliffs and coves of SLO can provide hours of amusement and discovery. 9 Since June 2000, the first Thursday of every month is The Bike Happening (also known as Bike Nite) in San Luis Obispo. People gather after the Farmer’s Market at the Mission Plaza with their bikes. One of the cultural focal centers of San Luis Obispo is the Christopher Cohen Performing Arts Center built on the Cal Poly Campus, which was constructed utilizing the donations of local businesses and individuals. Many high school and college programs are scheduled. Local artists perform plays, music and dance. The addition of the Performing Arts Center attracts many touring performances which are usually not found in communities of comparable size to San Luis Obispo. The Summer of 2007 was the opening concert of the Forbes Pipe Organ, which was built elevated into a side wall of Harmon Hall and required the donation of a further $3 million for purchase and installation.
