The phrase “parental discretion advised” is a surefire attention-grabber. When it’s used in conjunction with a lecture about alien abductions titled “Strange Harvest,” it’s begging it. This week, UFO expert Jim Ledwith talks about the 10,000 animal abductions since 1967—why are farms the target of alien research? Are extraterrestrials curious, or just really hungry? With actual footage of a bovine abduction and substantiating FBI files on the subject, the answers will surely be revealed on Tuesday, Oct. 22, at the Sonoma Community Center. 276 E Napa St., Sonoma. 7pm. $5—$10. 707.938.4626.
