Yes, I will be working in Reston. I don't want to do a lot of communting-that is the reason I would prefer to live in REston. The only thing I did not like in addition to expensive housing and rent is the apartment complexes. They are so big and an abundance of amenities. There are no 6 apartment buildings with no amenities -smaller apartments with just parking.
After reading the article, an old article, "commuting sentence" from the Washington Post forget it. I did think about living farther south in Va but then there is no train to take me to Reston. I also did like very much Leesburg (the city you mentioned) but that would be an hour commute to Reston-again no train.
