Normal Normal Snow?

Everyone agrees that we've had a lot of snow recently. According to one site, the average early February snowfall in Normal is around 6 inches. Regardless of the actual amount of snow that we receive, what is considered normal snow in Normal? Is it determined by how often people have to clear their drives? Is it determined by the number of snow days that the local public schools take? Or is it determined by the number of newspaper articles focused on how people in the area are dealing with the snow? Maybe there is never a "normal" amount of snow, just a "normal" amount of grumbling about winter weather!
