Another vote for Loudoun. Look at Eastern Loudoun County (just west of Dulles) from there you aren't all that far from the Silver Line (and it will be coming out further shortly). The SL is nice, although there is a cost to it, and I'm not sure what parking is. LC has a nice bus service that runs both to Metro Stations and into the city. The buses are able to ride on the Dulles Access lanes on 267, which helps with traffic.Loudoun County and Fairfax County have some of the highest rated school systems in the Nation. Move there and don't pay for private school.
There are some areas in these counties I would avoid, not because they're "bad areas" but because they have a heavy Spanish population (i.e. some areas in Herndon, Sterling and Manassas). No issues with Spanish speaking kids I just personally think it makes adjusting to a new place harder if there is a large majority of kids are speaking Spanish.
I'd consider places in Reston, Ashburn and Vienna first if you're looking for really good schools.
I live out in Leesburg, and my wife commutes to Tyson's Corner, and she goes on Rt 7 to avoid paying tolls. She deals with the long drive by working from home 2 days/week, and will commute via toll roads if time requires.
We love it out here with kids. Loudoun schools are great. Leesburg has a small townish feel to it, but you aren't far from anything you need.
Oh, and we have Wegmans. [/thread]
