Giani, you have to understand that in Canada we just carry on through Winter, the whole place doesnt just shut down as per your part of the world when a bit of the white stuff falls, as to the terms used to describe the runway conditions they seem to be pretty simple to most of us, regardless of the fine points of grammer, even the braking action reports sometimes are a bit graphic {"slick as snot on a tile floor" springs to mind, given by a tower controller on the East coast} so rather than nit pick about the terms used, just plant the sucker on the numbers, feet to the floor to make the anti skid do its job and reversers in the first class cabin, and see what a nice job the sand does on removing the paint!
