Should they be banned on tracks. HOL has turf grids with it and this does not so they're different. HOL's surface water can percolate down through it. It takes us all night to do. At the break we water and harrow, and we have 3 breaks, also we water and harrow during the races, starting all over again after the races.
Water runs off instead of going into the surface.
I think that is a wrong perception. I never do that. I can only tell you that the tracks I take care of, I don't do that. Yes the chute. One needs it more than the other, the chute is done as needed.
