Tim,
I saw the pictures you posted from your hunt last year.
You are hunting some nasty stuff and really working for your elk if you are hunting the same area this year.

For a hunter who is driving to a water hole and sitting there all day and not really doing much he may get some benefit from scents and cover up.

For the hard working hunter who is busting his hump over the country just to get to the elk, no amount of scent is going to cover you. It is just one more thing to carry and have to mess with. Keep it simple and play the wind.

As I am sure you already know once an elk gets the slightest scent of you he will be gone, and keep on going.

Good luck on your hunt and if you get the time post pictures.
Really enjoyed your shots from last years hunt.
That looked like a real adventure!!
