I don't know why, but I really find the color of the red clay to be unpleasant. Other surfaces that are green are much nicer to watch. And of course grass would be the best, with it's soothing green, cooler temperature, and park-like ambiance. But I think grass is supposed to be the most expensive surface for a club to maintain (yes?), so that's probably out. I just wish clay came in some other color than this baking-in-the-sun red.
