My DD is only 1.5 but we have encountered a few homeschooler moms that have organized field trips and such on STX. So people are doing it here but it is pretty under the radar - probably the case in most places anyway. I am interested in learning more about homeschooling and unschooling, but we're a ways off from having to make those decisions.
There is a Waldorf-inspired preschool here, and there are some crunchy moms here.
Does that help? What resources do you need to unschool?
