Yeah, Pat I might try the vanilla idea. It would be easier than brewin my own. And I think I remember an article about this too, but I can't remember what they said about storage. I also keep my huntin clothes in a sealed tote with leaves and nuts, dirt and ashes so it stays untainted. But I still like the idea of making my own cover scent and tailoring it to my local hunting areas. It also makes a nice gift to my buddies who tend to buy everything they need instead of making it.
