As previously stated, not everyone pays for it. I know a few guys here that have a slam, couldn't hunt on their own to save their lives, still have trophies all the same.
Huntings a series of personal accomplishments, its not a damn competition and wavin slams and trophies around doesn't mean anything. The guy doin the most waving probably paid someone else to do the footwork on the hunt and they just pulled the trigger.
