Should you abandon a hunt if you get busted climbing into the stand and a deer continues to blow at you?

Personally speaking, I don't pull the plug on a hunt just because a deer is blowing at me.  I've watched a lot of deer become alerted by deer blowing, but they rarely bug out and run the other direction.  I've also shot a few deer after being busted and blown at by deer earlier in the hunt.  As long as the wind direction is still good for your stand, stick with it.  You never know what's going to happen.
