Yes!! I spent a number of years as a craft vendor 25+ years ago at Winfield it was always great fun, always seemed to either be REALLY HOT or REALLY WET!! I was usually under the grandstand, the music was always AMAZING. I am so sorry to hear of the Crayon Factory, it was soo neat, guess I must have gotten there the last time just before it closed... to sad and I am sure it made a great impact on the local economy.
Check out Woolaroc Museum, Outside of Bartlesville and OSAGE Hills Park. There use to be a place out on the Cimarron River by Perkins that did trail rides, and had a famous "hideout"... but don't remember what it was called.. check out the following for ideas.
