I've been having a similar problem. Big stinky boars everywhere, but few sows. I did finally get a shot at a big sow, but she made it 50 yards into a big tangle of undergrowth, and she was so big I couldn't get her out of there. Then the grandson showed up for a weekend, and I put him where the hogs have been feeding on my corn. I heard the shot, and he walked out to tell me he got a medium sized female. When we went out to collect it, I noticed that, for a girl, she had some serious testicles. And stinky smelling. Well, the grandson is a starving college student, so we took the blackstrap and deboned the hindquarters and let the meat drain for 2 days in ice and salt. I had recently been told by a real crusty ol gal hog hunter that the approach would make the meat good to eat. After the second day, my wife cooked some of the backstrap on the grill, and it had NO gamey flavor. So, if your boar weighs under 150 pounds or so, try the ice and salt. We've only done it the one time, so maybe I just got lucky, but I will try it again.
