You don't have to play the whole time. But if you want to come out and play a set or two that's fine. Bring plenty to drink. There are restrooms and a water fountain.
You can enter the HS from Flourtown Road or Germantown Pike. Tennis courts are between a softball and soccer field.
Look out for the folks from meetup and go grab a court and start playing.
Please bring a can of newer tennis balls and plenty to drink. Also, don't forget your sunblock.
We will play Round Robin tennis either doubles or singles depending on how many attend.
