I've never been to this event, but I've been to the Cinco de Mayo event twice. Those events are a real blast, and based on the feedback I got from last years tomato event, it is a great one too.
You can purchase tickets here:
which includes a youtube from last years event.
Speaking of youtube's, my daughter Molly made it in the video from last years Cinco De Mayo three times :) (she's the sweet pea flower girl ! ) Proud Dad ! https://www.youtube.com/watch?v=eJDyZGJXhvk
It's about an hour+ from Sacramento, If planning on camping, and I recommend it, I would plan on getting there for 2:30pm. This is because one side of the orchard the trees are full growth, the other side minimal. Seems to be based on when you get there, and the full growth orchards fill up fast. Part of the fun is waking up in the orchard.
This isn't really a traditional camping event, the main reason for camping is to avoid the drive home at the end of the event. So don't expect a campfire experience.
This last Cinco de Mayo, I didn't even pack a camp stove. We did dinner from a taco truck, and had bars for breakfast until Woodland. Perfect carpool opportunity.
