could be the weather. the cold/snow usually keeps them denned up pretty hard. i hear of some trappers setting up right at the base of known den trees and setting multiple traps to get the whole crew of them at once...

im not a trapper, but run hounds...i know when its cold/snow on the ground, its hard to find a track...and it usually ends up being a den tree...here in PA were getting a little warm spell...might be a decint couple days for trappin...hunting with the hounds will still be tough with the moon...its real bright.
