This insulator came from a very recent hunt here in Oregon. Granted is is about 2/3 of an insulator, I wasn't going to leave it cause of that huge bubble. The bubble is also ballooned out on both sides of the skirt, and resemble a large growth on the insulator. It also has a great milk streak (not visible in this picture, but it is there in the picture), and look at the external carbon streak on the surface. Wish it was a whole insulator, but you know what they say about wishing.
