Yeah, I have a faded black T-shirt with a small Maquis emblem on one side of the chest. And nobody but me knows it is related to Star Trek. Unless they are familiar with the Maquis symbol that is. I also have a bright blue Niners baseball cap. Also, another subtle Star Trek piece of apparel.
I suppose it's my dirty little Star Trek secret. They see it. But they don't see it.
