Oliver Winery is hosting the Harvest Wine Festival, which they describe as "free wine tasting, live music, food trucks and winery tours all day. This year's entertainment lineup includes Jon Strahl Band, The Sad Sam Blues Jam, Phil Pierle of The Woomblies, Don't Call Me Betty, and the Muskett Brothers Blues Show."
Admission is $5 for the whole day (and I'm sure you'll need some cash if you want to grab some food from the food trucks).
It sounds like a lot of fun. The event goes from 11:00 AM-7:00 PM, so I figured maybe we could meet up at 11, walk around and check things out, grab some lunch from the food trucks and just kind of feel it out and stay for as little or as long as we want.
