I just want to be able to sell / display the print as an fine art photographer.
Selling and displaying constitute two separate and distinct (uses).
Displaying for purposes of self promotion, art galleries rarely require a release.
Selling (MAY) require a release. With the information given, my opinion is that you are safe to sell as a rodeo is a public event with no expectation of privacy.
"Associating" the images to forward an idea, endorse a product or attributing statements could create a problem. (i.e) If your photo of a rider being thrown from the horse had the caption " Fraud in the rodeo"...you might have a problem. Placing the photo with a photo of a bottle of coke, inferring rodeo riders like coke, would get you in trouble with coke and the model.
Check with the rodeo organizers..a simple question will often yield your answer.
No identifiable face?..No, no release will be needed.
Not selling to agencies or publishers? Just on your own?
I see no problem.
Creating a calandar for sale in mass production? I see a problem. :)
