Last year, 2 days before rifle deer season, 3 buddies, my dog, and I tromped around my property, and put up a ladder stand.
Wasn't gonna hunt there till later in the season, but things changed.

The next morning I shot a 170" buck, from the same stand, not 50 feet from the gutpile from the day before, almost right where the 4 wheeler was parked.
I'm not sayin they didn't smell us, but I don't think it mattered too much.
On the same note though, I've had them come upon the trail I walked in on, an turn around and bolt, so .......
