Soooooo, my question is why only the two options and they are polar options at that - domesticated pig vs wild deer?
I would say, because, BEEF is insanely priced! In our house BEEF is a luxury anymore! $5.00/lb for 15/85% burger. $6.00+ for 7-bone/Blade/chuck. Insane. For a steak we do Chuck Eye.
Chicken is, well, CHICKEN/BIRD...Dirty bird.
Lamb, I love lamb but Wifey doesn't really care for it and it's as bad as beef price wise, and greasier.
Just the name "P-O-R-K", sounds good.
