I took some 3" white letters and put BOC in the center of my boat windsheild. I did it because I haven't found any other BOC stickers, and I wanted one. It looks good, and I was wondering if anybody else had done this. Because a lot of times there are other members on the same water at the same time as you. This is a cheap simple way to indentify a member. I thought about putting one on my truck too.
