THE SOLUTION

I opened a can of worms mentioning the dance floor, but I have good news.
There is a new product called ‘Tired Feet ®’ that totally solves the problem of dust. It is a kind of rubber cement made out of discarded tires that comes in 50 lbs bags. I have done some calculation and I think we can cover the whole area for less than $100 and it is guaranteed to last for five years.
The application is very easy. Spread out in a thin layer it will bond with the earth under the influence of the sun’s heat and form a bright green, resilient and absolute dust free covering, something like Astroturf but softer and springier. The chemical process activated by the sun takes only between one and two hours during which one is warned to not walk on the surface as one could get stuck permanently.
