Dozens of people in light blue shirts flooded the San Diego Council Chambers on Wednesday to oppose a proposed tax on second homes and vacation rentals. Those people showed up to oppose Councilmember Sean Elo Rivera’s proposal to put an $8,000 tax on some vacation homes that failed. They weren’t San Diego residents – and they didn’t show up for free. She traveled from Los Angeles to San Diego the previous evening, she said, with 45 other people with an LA-based group called Urbano Strategies. According to its website, Urbano Strategies focuses on teaching Los Angeles residents how to be leaders in their neighborhoods.
