There's 3 out of 6 poles left out by my father's house with clear CD 320 Pyrex on them. 15 years ago a storm took down 3 of the poles with these on them and I managed to save 1 piece. The rest were destroyed from the fall. I've been watching these pieces since I was 11 years old(1981) to get them. Hopefully the power company will eventually come out and replace them and I can save the rest
