I made some of this last year...I made some with boiled pine needles also for a cover scent.

This is the first I have heard of this but, sounds like a good idea to me.
I will have to try it. I have always liked to use woodsmoke for a cover sent. Here there is a lot of small camps that burn wood to keep the
chill off at night so the deer are used to the smoke. I would have a small smudge burn to get the smoke on me and then put it out. Then head out
hunting, this has worked well for me.

Thanks guys! The article I found that had the recipe said not to use the brown bottle stuff as it contains a little odor. But if the brown bottle stuff works, better yet ...it's alot cheaper than the pure stuff.
