Does a deer that smells a person at 100 yds react the same to one he smells 800 yds away? I say no, the work you put in being scent less can make you smell like your 800 when your only a 100 yds away.

if nothing else makes sense, this does. I don't go to extremes but do use scent free detergent and soap. Hunting clothes stay in air tight container until I get out of the truck. I personally don't use cover scents because i have been busted more using them than without. To each his own
