I snip off a bunch of pine branches then roll the needles around hand until they start to stink like pine,,, if going in I will rub these all over my clothes and when coming out I roll them into my wool clothes before I put my clothes in bag,,,, I field dress as much as possible but a great cover up scent.
I also grab a big armful of dried leaves from the area and from a place where nobody parking would piss on the ground,, the leaves have a nice woodsy smell also.
other than that I don'[t spray nothing on my wool.
