WOW! what a change from when I lived in Chantilly!
I graduated from Chantilly HS in 1979, joined the Marine Corp and haven't been back since. I am sure the whole place would be alien looking to me now. Didn't even go to my 20th high school reunion because I wanted to keep my memories as they were.
I will keep my memories of 28 and 50 being mostly wide open fields; going to Downs store after school before they built the Dart store area in Brookfield subdivision. Heck, when I worked at Dulles Airport I would drive by the Redskins training area. (I understand that is no longer there)
Met my husband in the USMC, he was from Fairfax, VA, been married 25 years and counting! :-)
28 and 50 interchange is a traffic-choked nightmare surrounded by big-box stores, corporate office parks and cheap airport hotels.
I should know, it's right down the street from me. Sigh. Off to fight the traffic over there for my son's music class.
