On my way to a conference in Steamboat Springs earlier this week, I spotted what appear to be CD 1070's in clear and Hemingray blue. Out of the hundreds of miles of lines I've searched or looked at, this is the first time I've actually seen this type of insulator in use. I don't imagine they will last long, as the line is in disrepair and laying on the ground just a few poles away. Too bad I left my aluminum ladder at home!
