As summer gears up, so do the Knoxville Recreation Center’s swimming lessons. Nancy Kecy, a water safety instructor at the Rec Center, says that they have swim lessons available for all ages, starting at with a one-to-three year old child-parent class and moving up based on skill levels. Each class is a half-hour session that runs five days a week for two weeks. The next session starts on June 20, and classes will run through the end of July.
