Gymboree

"Gymboree began in 1976 when Joan Barnes, a mother from Marin County, California, tried to find a safe, fun place featuring age-appropriate activities for parents and young children to play together. Unable to do so, she did what any enterprising person would; she started her own program!" (Source: Internet) Easier said than done. Methinks for every Gymboree that succeeds there must've been a myriad of backyard-trampoline tryouts that failed.
