Unfortunately, I do not have a date for a Doubles tournament in mind. I can say for sure that it won't be in August.
We are likely moving the Plainville location in September so that's probably going to be an event light month. If we re-open in our new spot that following October / November, you can expect a Doubles event to follow that.
I don't have a lot of scheduling details due to the move. Lots of things are still up in the air at the moment (like when and exactly where).
