You see, Blue Note Napa wants to make sure everyone has a safe and enjoyable experience, so they've implemented a pretty strict bag policy. No large bags, backpacks, or anything that could potentially hide a picnic basket or a portable jazz band (okay, maybe not that last one, but you get the idea). It's all about security and safety, folks!
Now, I know what you're thinking, "but what about my essentials?" Don't worry, they've got you covered - you can still bring your phone, wallet, and keys, just no massive purses or giant man-bags. And if you're planning on bringing a camera, make sure it's a point-and-shoot or a phone camera, no DSLRs or tripods allowed - they want you to enjoy the music, not get too artsy!
