I'm not sure if these are in other areas of the country but here in North Carolina we have OBX stickers. OBX is short for The Outter Banks (Cape Hatteras, Kitty Hawk, etc). They are black and white oval stickers. There are now other areas that are doing the same thing with the 3 initials in black and white.

What do you all think of having CDH on stickers like these? We can do stickers, magnets, t-shirts, etc.
