just last week here in mn. it was cold! but the best part of that was i saw alot of deer and NO other hunters! i got on some deer but didnt let one fly (muzzle loader)., then this last part of the week and it warmed up ., and all the hunters from bird hunters to deer hunters were out ., and i didnt see any deer either., i like to hunt the cold the colder the better., deer feed,., bed to feed ., feed to bed!! easy to pattern~!
