T.O.
Blue Valley Recreation center offers both classes and an open gym. They are very reasonable for both residents and nonresidents. They are located on 151st ST, their website is www.bluevalleyrec.org. Also, if they like to swim the Matt Ross community center in OP off Metcalf and Marty (near 81st St) has a wonderful indoor pool with a two story slide. I think they also offer classes but would probably be a further drive. Good Luck and congratulations on your boys!
