Grit/sand/salt on their own are useless when you get more than a sprinkling of snow. For larger amounts, you need to shovel the snow and *then* use grit etc.
That's not to say that some areas are more prepared than others, but you have to take a lot into account: how much snow was there, how quickly did it fall (a large amount of snow falling slowly is easier to deal with than a smaller amount of snow arriving in a blizzard), was there also wind (drifts can cause problems out of all relation to the "nominal" depth of snow), when did it fall (fewer staff overnight) etc
