Share 'Tennis around Annandale, VA area'

I'm visiting my in-laws for the next couple of weeks and was wondering if anyone wanted to play. I'm in Annandale but don't mind traveling around Northern Virginia. I'm a 4.0 male. Played in HS and have won a few singles/doubles tournaments in SF where I play 4-5 times a week. Sets or rallying works. I just want the exercise. Thanks.
