I fear the noise much less than my scent drifting. Elk are noisy when they move. They pace themselves for the situation. Plan ahead, if you can't see 50 yards, you better creep if it's after a couple hours of light and elk are wandering. If it's within an hour of light and they're tracks are in a line, they're moving to feed or bed and faster than you will travel.....so boogie.
Wind is always 10x worse than noise.
