Finding someone to play duets with?

Hi everyone! I'm wondering if anyone has suggestions on how to find a community band or another musician to play flute with? I am an adult at an upper-beginner/intermediate level, and I’m looking to improve my skills and get more playing experience in addition to my regular lessons.
I am located in Northern VA and looking for opportunities across VA, DC, and MD. I already know about the Flute Society of Washington, so I'm looking for other local groups, casual ensembles, or duets. Thanks in advance!
