First, though I have no need to say this to you because you know it very well, there is NO need to apologize for shooting a high fence elk. Anyone who wants to use the "You bought it" argument should be invited to follow along on your next hunt and see if THEY still feel like you simply bought it!
One of my friends spent 6 weeks scouting elk last year, found a HUGE Oregon/Washington border bull in his area, only to have the bull flushed once the section was closed for scouting by a game wardens son on a 4 wheeler. He never found it on his hunt, but one of the farmers living close by told him what had happened.
He hunted the section, never seeing a bull, then 2 hours before closing, on his walk out, saw a big animal bedded down in some bushes. He got in close and found it was a 6x6 bull, which he promptly took. As he was taking pictures, he realized the bull had bedded down in the brush just 10 feet from the edge of a wheat field. They literally picked him up, moved him 10 feet and then drove a pickup to him! It wasn't the 7x7 he had hoped for, but it was a great elk. AND, he didn't have to haul him out! His elk was a lot easier to harvest than the high fence elk you got, and his was a natural, wild hunt!
As for your Dad, I'll be happy to be the first to contribute to a "Kirby's Dad Elk Hunt fund". I feel the same about my dad as you obviously do yours, and know my own sacrificed for his kids. He doesn't hunt, but we enjoy shooting together.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
