I played a (friendly) match yesterday with a friend of mine at his apartment complex tennis court. I took a ball and started dribbling it with my racquet and noticed it had the weirdest thud to it. At first I thought there was something wrong with the balls. I looked at the the surface some more closely and realized it wasn't a concrete hardcourt. It looked like concrete, but played much slower. It wasn't entirely unlike clay in the way that it played. I noticed it looked it was an asphalt or concrete surface with some sort of plasticky/rubber layer on top of it. Have you guys ever played on this surface? Yesterday was my first time and it threw me for a loop.
