Its not quite casino or rueda but I know there are a few folks in this community that would be interested in Kizomba and Bachata.
These events are coming up in August (hosted by the Century Ballroom):

Kizomba Workshop (Beginners) on Wed 8/5 from 8:00 to 9:30 $15: Check out this Facebook event
Kizomba / Bachata Social with Carlos Cinta (a really awesome bachatero!) on Fri 8/26 from 9:30 to 12:30 ($6): Check out this Facebook event
Bachata Weekend with Carlos Cinta on Sat 8/27 and Sun 8/28 (Timing and Cost TBD): Workshop details available in this Facebook event

If you’ve ever wanted to learn musicality and Dominican Bachata – there are the workshops for you. Carlos is a great person and has such a passion for bachata- its contagious! He’s one of the few bachata dancers I know, who uses his feet to “jam” with the music 🙂

Hope to see you at one or all of these events!
