The wind was about 3 to 5 mph, quartering from about 2 o'clock. Visibility was good with clouds above. My treestand put me about 30 feet above ground and my stand's safety-rail/armrest gave me near-benchrest stability.
My stand is in a white pine tree where one side of the marsh meets a small woods. A few evenings earlier from this stand I had watched 2 small yearlings chasing a doe just 60 yards out from me. Now, while still dark out, I had been forced to cough once and worried about what that did to my chances for the morning. A few minutes later I had heard one deer crash into the woods, going away from me. In this stand I could expect a shot at a deer as close as 30 yards or as far away as ...
I used my Zeiss 10 x 56 Night-owl binoculars to glass the marsh even before there was good shooting light, hoping to see my pre-selected buck heading home to his bedroom just before dawn. Discovering where he was settling down would give me the patience to wait for him to stand up and expose himself in his "safe" bedding area sometime during the upcoming day. He wouldn't expect danger from 30 feet up and perhaps a quarter mile away.
Dawn came and I still had not seen him. The time was now about 6:50 am, 15 minutes after the start of legal shooting time. Then I glassed again in the area across the marsh where I'd seen him briefly Sunday, just before dark.
