Local team has one down here and they now play far better football. You can tell the teams that prefer "the real stuff", they rock up, hoof it down the pitch, loose the ball and find they have forgotten that football is supposed to be played on green stuff not mud and in the air.
In the long run more of them the better for me , better financially for the clubs as the pitch is played on every day and the quality of play is higher drawing in more crowds.
