Another curious obsession

It’s fashionable for people in areas which get snow to make iced coffee using freshly fallen snow. It’s also fashionable for wonks to go on about yellow snow.
    Are we really supposed to believe that there are vast gangs of animals running around in gardens everywhere, pouring out vast quantities of wee to turn every area of fresh snow into a yellow health hazard instantly?
    Maybe the wonks should get a life.
