Welcome... There is one, but at the moment it is "quiet" waiting on some new folks to spin it up again. The Villa is a great place to live, quiet, but nearby to everything. The Park is awesome - lots of trails out there and a rare undeveloped area in central Fairfax. The City also has a large number of events and activities and parks for the kids also. There is a page (although it is minimally maintained) with community information:
