It is an interesting view and one that I share to a degree. I do believe that in more densely human populated areas the affect human scent has on deer is lessened. I still don't throw out the consideration for where the wind is blowing either. Now I won't sit at home if the wind isn't perfect, or I'd never hunt as the guy you mentioned said. On the other hand if the wind is dead wrong I usually try to have another back-up stand in the area that I can hunt that will give me a better chance with that wind. It's hard to argue with that guy's success, but I'm not quite prepared to abandon what I've been taught over 20+ years of hunting.
