This subject also reminds me that I favor lures with a reasonable amount of skunk musk in thier formulation whether it is in July or January. I used my Coyote and Fox Super Range All Call lures which contain skunk musk during the hot Summer months for 25 years during Michigan's bounty era. In my opinion, the addition of subtle skunk odor makes the whole set scenario seem more natural and works as a natural suspicion remover. One has to use reason when formulating lures with skunk musk or it will simply overpower all of the other fine working ingredients contained in the lure. If one is going to tip the skunk musk bottle and pour it to a lure then there is no sense in bothering to add such ingredients as asafoedita, castor, muskrat musk, tonquin, ambrette, valerian, muscaro, civet, etc., all one will end up with is a skunk gland lure in a base smell that has been obliterated by excessive skunk musk. From my testing and experience, it is all of those underlying multi-ingredient odors working together that ensure the best positive results. The skunk addition simply offers a longer call and suspicion removing quality to a good formula. Ace
