Hello, I'm Materialscientist. I noticed that you made a change to an article, Guerneville, California, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 04:54, 4 May 2020 (UTC)

Please do not add or change content, as you did at Guerneville, California, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. Magnolia677 (talk) 12:35, 4 May 2020 (UTC)
