We just went yesterday. It's $7 for adults $4 for kids 3-12. Of u want to see the bull riding and actual rodeo u have to buy a concert ticket because the rodeo is a few hours before te concert. There's a lot to see and do and be prepared to walk like a mad woman haha.
We rode the shuttle from Reed St. Its an all day ordeal. Wear comfy shoes because you'll be walking A LOT & if you plan on riding carnival rides wear closed toe shoes because a lot of them won't permit you on if you aren't.
