I am in agreement with camocop, I also would like to add that I think the deer know when it is deer season and when to be on full alert. When the woods that are normally quiet with no traffic (trucks, atv's, human's walking) all of the sudden start to get noisy, IMO they know whats up...Just my .02

I have had the same thing happen, this year I put up a new shooting house for my wife and daughter to huntout of and while I was up there putting in the windows (hammering, using portable saws and drills) I come around the front of the blind and I had a deer at the feeder at about 80 yards. There was me and another guy there talking and making all kinds of noise, the deer knew we were there but I believe it knew we were no threat as it was not deer season....
