It needs a sprinkler system or the dust brushing off to the side after every heat, at one point in the final i lost my car in the dust and was driving someone elses
. The hose last time never done much as its to big an area and drys out to quick with the buggys going round and a bit sun.
A spinkler sysem could cost 100s pounds 10 brooms would cost under 40 quid.
