E.S.
C., I don't know if you're still looking, but the Lenexa Community Center has a wonderful "Gym for Me" program on Mon. & Wed. mornings. It's only $1 per kid, and they provide all kids of riding toys (including a little coaster that uses ride-on cars) and 2 bounce houses, as well as balls and other toys. It's wonderful, especially when the weather is too bad to play outside!
