I use a digital scent monitoring device instead of that garbage. Just put your finger in your mouth, remove, hold it out. Whichever side dries is the direction you walk. Wonder what Fred Bear would do? He had the best camo ever!! Let's see.....

Khaki pants
red/black flannel
brown hat
boots, or in the case of Africa high-top basketball shoes...black of course.

too bad he missed out on scent lok, he could have been a legend.
