Caught this one today. I had the box in a culvert and had to slide in there headfirst cause of the snow. There were lots of tracks in the culvert and around the box. The box had been there for 2 weeks and had no action. I was actually going to pull it today if there was nothing in it. I reset it and set another in the culvert right next to it.
Seems like if I check the boxes everyday, I usually have empty boxes. If I wait about 3 days between checks, there is more activity. Also, my Moose River lure came in today so I rebaited/lured everything real good. Think I'll wait a couple days to check boxes again-when it warms up a little. (It was freakin -40 this morn. and supposed to be at least that tom!)
