Oldshed- I understand what you are saying, but that's not necessarily the direction I hoped this would go...
As mentioned, I pay attention to scent control even during firearms season. Year after year I've known guys who don't, some of whom even smoke cigarettes while on stand, yet routinely see & harvest good deer.
While I try to approach my stand based on wind direction & as quietly as possible I've also seen folks ride an atv in, park next to their stand yet also see/shoot deer. Not just during firearms season either.
Unfortunately, this suggests to me that skills may not be as important as luck.
