If a stronger scent could cover a weeker scent a deer could smell where you or another deer walked. Try walking across a corn field. Now go back and put yournose to the ground and smell where you walked. What do you smell? Thats right...dirt and cornstalks. These smells are very strong and you can't smell the very weak scent you left but a deer can smell the scent you left with ease even when its mixed with the much stronger scent of the corn and dirt. Its the same when you squirt a little cover scent on yourself. You cant cover your scent....
