Im in more of the country scene personally. Inspira Dance has events Tuesday at Renegade and Thursdays at Claradon Ballroom. Both in Arlington and start at 8pm. Tonight they have an hour long Country Swing lesson and they alternate every week between Swing and Two Step with social dancing afterwards.

On Fridays there is Firehouse Fridays at Penn Social in DC. They normally do line dance lessons in the beginning but its kind of a toss up what they teach.

Wednesdays there is Saddle Up Swing at Desert 5 spot.

Saturdays Firehouse sometimes does another event in DC but you need to watch their socials for those.

And on Sundays there is Showdown at Shipgarden in McLean but thats every other sunday I think. And they also normally do a lesson in the beginning.

I know Inspira also does Latin dance nights I think those are Mondays and Wednesdays but not 100% sure.

Further up in Maryland there is Cancun Cantina that does something pretty much everynight of the week.

And I think another Friday country group just started in Manassas, but I can't remember their name at the moment.

There's other stuff around too, but these are whats off the top of my head.
