GR8,
I never gave that much consideration, but it definitely deserves a close look. Where I hunt in Missouri, I have about 1 1/2 to 2 miles of trails to get to where we hunt. I have to ride a quad in. I just got a new one, and I plan to take pains to keep it clean and de-scent it as much as possible. I know it's not possible to eliminate all the smell, but if I ever spilled gas or oil on it during hunting season, I'd be scrubbing it down and giving it the same treatment I'd give myself. Maybe I should take the advice of some of the others and have my hunting garb in a sealed pack and put it on when I get to the stand.
