This court is right behind the park and shop - between Kennedy Road and MacDonnell Road - across the street from the Biological gardens. I think it might be officially called Kennedy park. But to get to it - you either walk up stairs from Kennedy road - follow the signs that say to YWCA or walk down the stiars from the first left you can take on Macdonnell (it's a one way street).
I unfortunately cannot make it today since I have something going on at 2 pm. Maybe you guys will still be playing afterwards? Or even better - it will be such a good game that it will turn into a weekly event!
