The show, a traditional kickoff to the summer season and a showcase for World Grand Championship contenders, expects attendance of over 6,000. It will run through Saturday night.
"The Fun Show is a wonderful showcase for many great horses," said Celebration Board Chairman Henry Hulan in a news release. "For some it's the beginning of a championship campaign, and for others it could be considered a 'coming out party' for many of the talented, young horses."
The show has long been noted as a springboard for many of the top horses and riders on their way to earning World Grand Championships.
Just as NASCAR and Professional Bull Riding have their leader boards, so does the Walking Horse Trainers Association with its Riders' Cup. Last year's Rider's Cup series winner Jimmy McConnell is once again leading the field over 2010 reserve winner Charlie Green, with Tim Smith strongly positioned in third.
Trainers showing at the Spring Fun Show are eligible to earn double Rider's Cup points.
Final preparations are being made on The Celebration's grounds and facilities by grounds crew headed by Wade Adams. Freshly mown lawns and fields, plants and flowers, and well-maintained facilities will greet visitors.
Nightly performances begin at 6 p.m. and vendors on the arena concourse will open at 5.
