Went up to the camp last weekend for a work day and a little trimming of my sons stand. He was using the gas powered expandable tree saw when not 40 yards behind him were two big bucks. They just put their heads down, had someplace to go and we were in the way. So as they calmly walked around us, we used them to pick out our firing lanes. He's gunning the motor to see their reaction, and they could care less. It's like we paid these two deer to walk to every firing lane possible, and it worked at least for 180 degrees of his location. It really depends on the area you hunt. Our club has houses surrounding the area. The deer are already use to people with chain saws, quads, etc. It seems they don't spook as easy as they use to, not that I'm complaining.
