With his dad as an interested spectator, 11-year-old Matt Willden (left in above picture), duels Nathan Day with foam plastic swords Saturday during a family F.U.N. day at Liberty Park. Meanwhile, 5-year-old Paul Searle, left, gets a boost from Jazz player Thurl Bailey. The day was sponsored by the Utah Governor's Council on Health and Physical Fitness and Salt Lake City Parks and Recreation to promote the fun aspects of Fitness, Unity and Nutrition.
