All right. I fully agree that having wing memorabilia before getting wings is a no-no, and guaranteed to get s*^t from IPs. Let's not even start on personalized license plates with things like "gotafly." If I had found out whose car that was, he would've gotten a down just for gayness.
However, this weird pagan mysticism thing in this thread and the superstition thread is striking me as really weird. Yes, wings are important symbols, but they're also just pieces of anodized metal. As long as you don't walk around flashing them at people, take it easy. Your flesh may touch them before your winging without getting the evil eye. Put them on your bulletin board for moto, whatever, even pin them on in the provacy of your home. Just don't go tooling around town with them.
