If I'm not mistaken, the first few areas you talked about are in the wilderness (16b), correct?
I think I've seen your Negrito buck (or his progeny). It was an archery elk hunt, and while walking through the juniper back behind the air base I came face to face with a huge buck at about 30 yards. I honestly thought it was an elk, so I just kept walking a few feet until I was behind another tree and gathered my thoughts. I replayed the scene in my mind and realized, "no that was a huge buck!" I circled around and saw him again, one of the best looking bucks I've seen anywhere.
That being said, I've hunted either deer or elk in 16 every year for the last 3 years (this will be the 4th), and that is the only big scoring buck I've ever seen there. I've seen large-bodied bucks with disappointingly small antlers up on Bear Wallow mountain. I've seen herds of doe and juveniles in 16e. Just never seen those monsters. I've repeatedly heard talk of some Coues deer, but when I try to get locations it ends up being private areas along 12 between Reserve and Apache Creek.
Maybe this year will be the year.
