Never even thought about keeping anything as a trophy. Lucked up and made an eagle on the third hole of my first ever round of golf (and didn't even know what an eagle was). I just figured people made them all the time.
A friend of mine bought himself some kind of a trophy for a double-eagle he made and that was the first time I ever knew of somebody buying themselves their own trophy. I had to give him a sideways glance.
(Seemed a little weird to me).
I figured trophies were something they gave you, for leading the league in something, to take home and show your mom so she could stack them in a closet somewhere to gather dust.
