You are so right, turkey hunters are a very special fraternity and certainly lean toward the helpful side. Maybe it's because they know that the odds are still stacked in the gobbler's favor no matter what advice is dispensed. And you still have to get the big bird within 30 yards no matter what your hunting style is.
On the other hand, deer hunting seems to bring out the worst in folks. Around here camps are sharply divided on issues of shooting does and small bucks, baiting, etc. Old timers believe real men don't shoot does and you gotta get your buck at all cost...even if it means shooting a forkhorn or basket rack 6 point. The DNR and QDM want you to shoot does to control the deer herd and let small bucks walk. (Which also happens to be my philosophy.) In any case, most are not willing to help you and are very secretive with information.
My father just hosted two old friends from South Carolina on a Michigan hunt. These two southern gentlemen have hunted all over the country and did indeed reflect on the community feel that turkey hunting fosters. One sentiment caught my ear- "I never met a turkey hunter that I wouldn't trust my wife and children with." While that may be an exaggeration to make a point, you just don't hear those kinds of statements made about deer, duck and rabbit hunters, or even fishermen.
