The only reason I am bringing these points up is because in this sport, it is common knowledge and courtesy to return marked plastic. A person who has played for, say, 16.5 years should #1 know this and #2 set a good example for new people joining the sport. In my understanding, it has become uncommon for lost plastic to be returned. There's a reason, guess what it is. I am new, and have made every effort to return every marked disc, no matter where or what it is. I have no idea how long it has been there. Do the right thing and atleast try to return lost plastic, chances are you will be given the disc anyways.
