Arlington County in Northern VA has a great tennis association that has a spring and fall mixed doubles league as well as singles and mixed doubles ladders that run from April thru October. You can visit ACTA for more information. I usually play 2x a week but would love to play more if anyone is interested. Just post here. Thanks.
Don't know much about it or anyone here in the DC area. I am just getting back into playing again. I will check out the ACTA site. However, if you need a hitting partner, hit me up. saybisous@gmail.com
