My family and I took a vacation to Korea. I never thought I would find insulators but luck was with me. We were walking around a couple markets when on one of the streets a line crew was working on a pole. As I was walking up to the crew, I could see the back of the truck was full of insulators. A huge thanks to Google translate because the line crew didn't know any English and I don't know any Korean. I typed in Google translate, "I collect electrical insulators, could I have one?" and it worked!
