A.S.
Hi L. - welcome (in advance) to the East Coast! I've been in Virginia for the past 25 years (moved from Michigan). I have 4 kids (14, 12, 11 and 11) and live in Kingstowne. It's a great community and a wonderful school system. My youngest go to Lane Elementary School. (Fairfax county school system - which gets great reviews.) Kingstowne has access to fitness centers, pools and community centers. The public library is really close too.
We've really enjoyed living here - and there are plenty of kids. Good luck with the move.
