I discovered today at Trophy Lakes that a person in our Club found one of my discs (at a different course), scratched off my name and had been playing with it. The only way I found this out was my disc was turned into the pro shop at Trophy Lakes after someone had dived for discs at the course. I do not know the person who wrote their name on my discs but someone told me the person recently joined our club. Any suggestions on how I should handle this so it does not happen to anyone else. I plan on talking to our President about it but I do not want any bad vibes or to isolate anyone.
