upwind is the ONLY scent control that works
rubber boots seem to help
sprays and clothing etc is a joke IMO
I think you mean downwind, and I've had deer bust me when i'm downwind, and i had a 6pointer nearly run into me from downwind surely it has to do with the deer I've read they have days where they're senses are sharp and days where they have a stuffy nose aye?
Scent control is key!
