I can rent outdoor tennis and indoor squash courts at the University of Pennsylvania for free. The squash center has everything you need as free rentals (shoes, racquets, and balls). The tennis center unfortunately does not, so you would have to bring your own equipment. I have extra tennis balls and one extra racquet. This is an informal event and can happen whenever people want and at whatever frequency people prefer. I also do not need to be present for the event to happen. I can book courts for people to use if you want. The times below are just suggestions. Please let me know if you prefer other times. I'm always down to hit! Feel free to contact me at 573-514-5428.
