Matt Lewis was up late worrying last Wednesday, the night before what could have been the final meeting for the Briones Lions Club after 51 years of community service. As president of the Bolinas-Stinson Beach branch of the international organization, Mr. Lewis, who has been part of the club since 1989, said he was bracing himself. Over the last few months, he had worked to boost membership, but if he couldn’t raise the club’s roster by 17 members by the meeting’s close, the club would fold. “Basically, this was the last call,” he said. “I thought it was going to be just okay, but I was flabbergasted. I had to call [my wife] and tell her to bring us more applications!” The struggling club, which recently had just six active members, saw close to 40 new and interested people last week. And to Mr. Lewis’s gleeful surprise, many were younger 30-somethings. Still, to become official members, applicants must complete “three meetings in a row without an unexcused absence,” and Mr. Lewis is also anxious to fill the club’s treasurer post and two of its director posts. The Briones provide eyewear to school children, coordinate cleanups around the lagoon and organize the annual Fourth of July celebration in Bolinas. One newcomer last week was Stinson Beach resident Kelli Giest, who caught Mr. Lewis’s “Do or Die” notices about the club on social media. “It seemed timely. We have to take care of each other,” said Ms. Geist, a Stinson Beach native who works in elder and hospice care. “And with a lot of houses becoming vacation rentals, the community we all grew up in is kind of fading.” Anyone else interested in the club can reach Mr. Lewis at [email protected]. The club meets on the fourth Thursday of the month at 7p.m. at the Bolinas Rod & Boat Club.
