I'd agree with OLD
17 (hehehe) on the gland lure. I have been using some of Asa's Nature Call all the stuff around lure and the dang fox keep getting in the sets

I would not hesitate to recomend this lure and ole Boggy sells it cause that's where I got mine.
In cold nasty weather, mating season or not a food base and or mixed curiosity lure still work fine. Call lures are a good thing in this weather also.
PS just saw you are in Ohio, you might get some of Stephs Cachatorie lure from T-man. Its a VERY strong lure for them cold OHIO nights.
