Found answer to my own question. The Decathlon Sports Club is a summer camp for boys and girls (I believe ages 6-12). They've been around since 1981 and I've asked around and continue to hear nothing but great things from other parents who've sent their children. I found their website at www.decathlonsportsclub.com and it's quite comprehensive. Anyway, if you're looking for a good, active, organized, safe, well-run and established summer sports camp for your children this one is worth taking a look at. I live closest to their camp held at Woodside High but, according to their website, they also have a camp location in Los Altos and I heard they offer free bus service from Palo Alto to that site.
