Any pigeon racers here?

There is a guy in town that races them. He is realy in to it and has made a lot of money doing it. It is amazing how fast they can fly and how far they can go and still find there way home. Well most of them any way. Some don't make it back and he don't want them back. Says they are worthless and if they cant make it home they cant win the race. Tells people just to shoot them when they call to tell him they are hanging around there house. LOL
