Before paved roads and motor vehicles were integral to transportation, steam riverboats transported goods and people through California—and Petaluma was a key destination. The annual Rivertown Revival seeks to capture the spirit of that era while also raising money to maintain the river and watershed that was once the site of bustling commerce. The big draw of the eco-friendly event will be a variety of live music, including blues, country, jazz, vaudeville, Latin, and bluegrass. There will also be an array of Sonoma County vendors, interactive art, a play area for kids, and the chance to dress up in zany costumes. The event will be held on July 20, 11 a.m.–8 p.m., at Steamer Landing Park on Copeland Street in Petaluma. Admission is $20 for adults and $5 for children ages 16 and younger.
