Was out last wensday and thursday and it was cold. Hunted the edge of a marsh (public land). Had 2 does come out of the frags about 4pm about 80yrds. They circled the wooded area downwind of my decoy, which was about thirty yrds on a 45 degree angle up wind of my hidding place, wind was about 20 mph. They stood in the marsh with their noses in the air for a good ten minutes just checking the wind. I have a tail wagger on my decoy so they caught the motion which is what got their attention in the first place. Thought they would continue in to check the decoy out. Nope ,They continued to circle and watch the decoy and every step they took, they stopped put their nose in the air and had those ears working. Got downwind of my position, about sixty yrds out and froze. I took a shower in scent killing soap, cloths hanging outside all season, scentblocker head to toe, and dressing in the field, and they still knew. Well they went back into the march. I watched them walk around in the march and meet up with some other deer. Then about 8 total came and the same exact thing happened again except for the big doe in the front stood their even longer starring right at me from about 60yards out downwind. Had my 3d asat suit on and did not even flinch. Well they went back in to the marsh. First time i ever saw that many deer on public land at one time. I was the onlu one in the woods, didnt get anything but still had a good time. Amazing, the power of that nose, And that was with 20mph wind at 60yrds or more. Went back to the same area the next evening, with out the decoy, and the didnt come out there but i had one come in behind me but couldnt get a shot. Would have been out on this past cold week end but had to work. They r there but diffently spooked, cant wait till next season already.
