(Video Below) The Simi Valley Days Carnival is a 5 day event that takes place the weekend after the Simi Valley Days Parade. Rides, Food, Music and shopping are part of the fun.
The more unusual event is the Cow Chip Bingo contest. You can buy a chance to win prize money in this event. How it works, is you purchase a square on a large grid. A section of the park is fenced off, marked with a grid and half a dozen cows are left to roam while the spectators wait patiently for the cows to drop their load on a numbered square.
