I am starting this meetup because I was part of the City Park tennis meetup last year, and like many, I was sorry to see it go away. This is the same concept; mixed doubles, if you really want, do singles, you'll just look a little antisocial. This meetup will have the added bonus of after tennis beers, or apres cocktails if that suits you better. They can conveniently be had somewhere on 17th Ave.
The start time is 5:30pm to 7pm - it's flexible.
However the apres beers time is 9pm or after.
