Someone just asked me what "snowing blue lick" means. It was used in one of the letters from the 1860's by a Chaumont woman. Does it have anything to do with the salt bricks (licks) put out for cattle? While trying to find an answer to a question about plank bridges????, my husband found this site from Ontario, Canada which you might find interesting: http://www.mto.gov.on.ca/english/about/footpaths/plank.htm I hadn't realized macadamized roads pre-dated plank roads, either. Learn something every day, don't we? Thanks, Shirley
