Our ice here in MO is about 4 to 5 inches thick, I didn't have time to ice fish but walking around on the ice and seen some otter sign where they come up out of the water in the ground and then come out on top of the ice to eat the fish they caught, fish heads and scales laying around, I put out a few traps in some strategic places, see if I have any luck, I changed my strategy up a bit on my muskrats and been catching them pretty steady, even a couple from under the ice.

All the really good ideas I've ever had came to me while I was milking a cow.
