If you are unable to attend the Big Blue Bucket Eco-Fair on Saturday, you can follow the events live on Twitter.
The fair, which runs from 10 a.m. till 2 p.m. at Jarrold Avenue and Phelps Street, is put on by the San Francisco Public Utilities Commission, the Department of Public Works, the Department of the Environment, as well as private companies.
But if you are unable to swing by the fair to pick up your free bag of compost, you can follow the SFPUC, which is posting details from the event live on Twitter.
