"Makes hunting a 360 degree sport"

Smoke is nearly omnipresent. Regardless of location, smoke is a common smell.
The burning of wood has occurred since the begging of time, therefore, animals DO NOT have a "flight response" instinct to the smell of burning wood. That is simply another myth put forth by Walt Disney’s "BAMBI".

Regardless of what brand of laundry detergent a hunter may use, smoke will over-power the fragrance.

There simply is no man-made odor that can effectively cover the smell of smoke. This is why many insurance claims are paid on furniture and other house-hold items that are apparently undamaged after a house fire. Although it is not beneficial to home furnishings, it is ideal for a hunter to smell like a natural, non-threatening element.
