Just now reading the COTM and all I can say is "WOW" Great history recount and awesome pics. Really love the cans. Anyway, here is my contribution.

Large early reflective sign. Two piece sign covered in crushed gravel like substance that is reflective. I always assumed it was mounted to a fence next to the early stations. I've only seen one other like this and any info would be appreciated. Thanks again for the great article.
