Mommy Pages is an online resource guide for all parents, especially moms, out there. It offers a directory of everything one might need in raising kids, from products to services. And yes, there's a lot of classes listed in their site (and handbook, which you get for free when you go to a Mommy Mundo event) to occupy and enrich your kids (and yourself) with.
So, if high school wrestling isn't being offered in your son's school, maybe you can find an alternative in Mommy Pages (like wushu, which I intend to enrol my son in when he's older). There are also classes now for budding fashionistas and theater artists. It's really a great time to be a kid for kids now, with all these options, and thankfully, the resources have been consolidated and listed down by Mommy Pages.
Just check out the website and get a free copy :)
