Snow fences and keeping winter roads clear

USA Today ran a story about a simple idea that looks promising. Better snow fences can all but eliminate snow drifting onto roads, minimizing winter disruption. This method is "100 times less expensive" than plowing, salting and sanding. The improvement threatens to make snow days much less festive for children, but we all must sacrifice as we grapple with climate change impacts.
