I had one blow at me on Friday morning about 5:30. I shot a doe at 8:15.
Unless that's the only deer in your woods....I wouldn't worry about it one bit. Here's what I do...and it's wortha a try, huh?
BLOW BACK!
When I get blown at going in OR out......I just blow back (in my best deer-speak). They don't have one clue "what" you are in the dark....and they might feel a bit more at ease if they think it's another deer.
WHO KNOWS?
