RE: Would you hunt this 170"-class buck with a bow?
IMO, you have about 2-3 days to kill the deer. His summer pattern is about to come to a screaching hault. Forget the pop up blind. That won't fool him for a second. You should put that blind up a month ago. You only option is pit blind, or do as Hazcon suggested, lay down and when looks away, make your move.
Don't screw around with this buck, you will only have a couple days. 1,000 to 1 odds you will NEVER see him after the first week of the season.
