I did not have a mentor or coach when I began bow hunting for whitetails. It has been all trial and error - my folks still do not understand my need/desire to bowhunt.
One thing that I have learned - deer are curious. I once spent over 20 minutes messing with a doe at ground level. I wear an ASAT leafy oversuit - and was on all fours trying to get close to a group of does.
One doe decided to "investigate" me and came within 10'. She snorted and stomped right at my head - I would not show my face - would look through the mesh of my hood.
I stayed still for a good bit and they decided that I was harmless (ha). I slowly rose to my knees and picked out a nice fat doe - sighted the pins and released.
She went about 15 yards and dropped. It was a very instructive hunt.
I have only been bow hunting for 12 years and I have found a group of does to be the most difficult to take. I am a meat hunter and boy are they tasty!
But I'll not turn down a nice buck that decides to follow a group of does through my killzone.
