Does anyone know of a public waldorf school?

I have an 18-month-old enrolled in waldorf pre-school and we are looking for more information on the few public waldorf schools around the country, but I can't seem to find them. Location is not important, we are just trying to figure out what would be a more budget-friendly place to live. Finding an affordable waldorf school will mean the difference between deciding to have just one child, or to try for more. Thanks for your help! Oh! And if you know of any waldorf schools that offer sibling discounts that would be great, too.
