Saturday is supposed to be a great day outside, how about some tennis?
Let's enjoy the summer days while getting some exercise at the same time. If you're not into tennis, then we could also play a game of frisbee, volleyball, etc, or even just come and walk your dog =)
Bring your racket and balls if you have them. If you have some extra rackets, please also bring them to cover the people that don't have them. If not, we'll take turns on the court.

aaand of course soccer... I'm bringing my soccer ball
