Yeah it's hard to make heads or tails of it sometimes. Like the spot in my pics above with the female caught. That snare is on top of a little open knob, making the snare loop as "sky-lined" as it could possibly be. But still, they keep walking into it?

Judging by my trail cams, most of the action where I have these sets is night time, so perhaps they get more use from their noses than their eyes for these particular sets. Down over the hill in the thickets of the river bottoms (where they bed), and where I don't have any sets, I get a lot more daytime trail cam pics of the yappers.

Trying to get some of these late ones (i.e. smart ones) I think my best strategy is to keep placing more new sets in more new spots.

Hopefully this snow cover will last a few days...it sure does help!
