Jamboree got it’s beginning over 50 years ago  a few civic minded community leaders joined together to form what is an outstanding civic organization. It started as a vision to plan a “Hometown Celebration” for the community of Smithville. In Jamboree's early days, Jamboree was held on the streets of Downtown Smithville, today known as “Main Street”. There were food vendor’s, a soda booth, street dances, jelly and jam contest, bread making, watermelon booth, chicken booth and many other events. In the later years, Jamboree was moved to its current home of Riverbend Park. There have been many civic leaders who have been a part of this organization in the past such as Max Jones, chairperson in 1969. He was joined by other individual’s such as Charles Ebner, Mr. and Mrs. George Mick, Mr. and Mrs. Nelson Scheler, Karen and Allan Bell and many more.
