So, has anyone done it? I have . On tuesday there were a match against this other school. We played half way when it started to rain. At first it was a light rain, playable. But it start to rain harder so we went in. But i asked my friend if they wanted to play in the rain. He goes sure. OH BOY. Was it fun. Sure, it would mess up my strings and grip but i really didn't care. I can tell you now, the balls move faster, lower, and you have to hit with more power. But make sure you grip your racket harder to because it will slip. All of yall should do this.
