I think Mr. Deer Hunter got it pretty well. I also think we really spend way to much time thinking about scent control and keeping our scent to an absolute minimum. Here is how I think of it, if you are scared to death of skunks, whether you smell the faintest of a skunk or a smell a skunk that just sprayed 10 feet away, you are going to beat feet out of where you are. Whether a deer smells a extreme faint smell of a human or an intense smell of a human, both times they are going to be running if they are scared of humans.

Personally, I just try my best to stay clean but don't overdue it. Play the wind and you'll be fine.
