i played at the court at Cambridge once as well i'm sure it's the only real tennis court in Cambridge... that game is best played when tripping on acid!!! it is crazy! Racquets are way heavy as well, like 400 grams, maybe even more. Kinda fun once you get the hang of it though.
If anybody gets to play it, don't even think about picking up a normal tennis racquet the next day, your arm will be dead!
oh yeah, it's well dangerous too... the balls are hard and don't really have a predictable bounce.
