Greys are not real smart, if you make exposed trap blind sets on the trails they use like you would for bobcat you’ll catch em
Ok so i cannuse exposed traps cause i thought greys were smart but i guess not i just have to get big traps with expandapans
x2
Yes. You don't need big traps I have caught plenty in 1 3/4's and 1 1/2's.
You might be able to get a dirt hole set (or similar) in that location depending on how deep the leaves and soil is before you hit big rocks.
Based off your picture this is how I would set it. I'm no pro and far from it so take it how you see fit lol.
The dead log would get an exposed trap at the top and bottom and more than likely on opposite sides (depending on terrain). I would tie an extension cable to the log for each trap. I would add small twigs to block the trap and cover the pan with a leaf or 2. The reason I would set there and like that is it looks like a perfect travel way going down to the boulder and up to the boulder ledge.
I would double check that boulder ledge on top and possibly make another exposed set there.
If I was to make a cubby there I would either make one between the rock and the big tree on the left or at the tree with "X" branches. I would pick those 2 spots because if the cat or gray is going up they would be flashy enough to investigate.
