Thanks. My wife is going to take the S up to Tysons on Thursday, I'll do a Range charge and she should be good, but I do have some backup charge places mapped our for her, and told her to drive gently.
Scott- I just posted a few pictures of a new Tesla area in the garage near Nordstrom that my wife took. There is a Tesla charger there. No idea if it's on, and it's certainly not intended to be public, but maybe you can get permission from someone to use it? The store isn't open yet.
Tyson's Corner store must be opening soon?
