Closest was around 3ft. Was still hunting the edge of an alder swamp on an old grown up logging trail. Thought I heard some noise ahead, so I took a knee and blew a couple of doe bleats. The noise increased in intensity for a couple of seconds. Then I blew a deep buck grunt. Before I could move, a nice 4x5 whitetail was running from the alders toward me at full speed. He stopped on the other side of the alder I was kneeling next to. He was as surprised to see me as I was to see him. I quick swung my rifle and put a 7mm 150gr Partition through him as he spun to leave.
