One other thing: In this modern world, is there no such thing as an affordable and environmentally-approved substance that can limit dust in a racetrack-type of application? Couldn't one of us with some farming know-how (rules me out) make a fortune introducing such a solution? I understand that the calcium chloride that helped numerous tracks in the past, has been banned, but in this age when toxins that can cause birth defects are routinely sprayed on food crops anyway, isn't somebody on the cusp of creating a soluble dust-deterrent?
