I looked at the Grayson website, and it shows that they have weekend enrichment sessions planned in which any gifted students--not just those enrolled at Grayson-- can explore fun topics outside a structured classroom with intellectual peers. That might be a good opportunity, if homeschooling, to meet like-minded people without making a large financial commitment or obligating your family to travel every day. The cost for a 6-8 week session is $200-300.
