I think maybe the scent blocking thing is making them so much money, they will have scent blocking butt wipe out soon. There are alot of things you could do like baking soda, or other options you could use that won't cost you any extra money. I bet just chewing some gum a half hour before you go out will get the saliva running and wash alot of the scent away. Chew an apple, or just chaw on some grass and spit it out.
