In 2013, Earth Day SLO had the largest number of attendees since the event began, in 1990. Records show that more than 2,000 people came out to celebrate Earth Day at El Chorro Regional Park on April 21. Free transportation for the festival-goers was provided by both SLO Transit and San Luis Obispo County’s Regional Transit Authority (RTA). Earth Day goers arriving at the San Luis Obispo downtown transit center rode on the Double Decker bus to Cuesta College. Hundreds more traveled from San Simeon to Morro Bay and Los Osos on buses or in carpools from throughout the county to Cuesta College where they hitched a ride on a trolley and shuttled over to the event. The smooth transition between the buses helped start off a successful Earth Day.
Throughout the entire day, both transportation services were giving free rides to anyone in the county. Usually $1.50 to $3 per ride, SLO Transit and RTA waved their fees to encourage the use of public transit and to help promote a cleaner environment and an eco-friendly lifestyle. According to Aimee Wyatt, manager of marketing and service planning for RTA, their plan worked as they saw an increase in bus riders on Earth Day. “It appeared that ridership for that Sunday was about 30 percent higher than what we’d normally carry on our regular routes,” commented Wyatt. “Everything worked very smoothly.” RTA also provided free rides through South County Area Transit, servicing the Five Cities area.
