As you said, lots of talk, not much action. And the ones who need to thin the most (baiters who artificially inflate the nest predators by feeding them incidentally) are usually the least likely to trap.
Most turkey hunters are takers and leave the flock in worse condition than when they started never doing much to help.
I started running traps every time I come up to hunt or visit. Set them the first night up, but have to pull in 2 or 3 days when I head back. Sometimes I get one or zero, sometimes 5 or 6. Dunno if I'm making a difference being so inconsistent, but it makes me feel like I'm doing a little on that end. My biggest contribution is habitat management and self imposed harvest restrictions.
