I take it that this post is refering to cover scents. i dont use them. why bother with a cover scent in a bottle. most everywhere, there are softwood trees. i always try to hunt out of pines myself, or hemlock. all you need to do is take your knife and scrape of some of the bark. not much though. it lets out a wicked stink that works great. every time you hunt the tree after the first time, just scuff up the pitch and its like a new scent post all over again. as natural as you can get. and if your not hunting in a pine, just snap a pine limb off on your way in and crumple up the green ends and rub them all over you. you will absolutely reak like a pine tree. best off all its fast, requires no planning, and its free!
