Neighborliness reaches new musical heights this Sunday in Napa. The 5th Annual Porchfest, a non-stop outdoor concert from noon to 6 takes place on 50 porches most within walking distance of each other. It’s a music sampler for all kinds of tastes –bluegrass, jazz, country, surf, new wave (is it still new after all these years?), plus a food truck roundup. It’s summer in Napa so be prepared to hydrate. Free.
