Will Winter Ever End?

February is almost gone but winter is not giving up without a fight.Colder again tonight.Dreary and snowy today. Riding in my arena is getting old and dusty.At the beginning of the cold weather I work compost into the sand to keep the dust down.It works for about 3 months and then it doesn't.I end up with a very dirty face.Soon I can add water to keep the dust down and the horses will be happier too.Have tried salt but have had no luck.Any ideas?
