If You were sitting where the red dot is and no Deer passed by You then they must be traveling and or bedding from the far end Your seeing them at?I'd set up a small ground blind in the tree line a little further left where You have the light blue dots...You don't want to be on top of the Deer if they are coming in at that far corner...the Muzzle Loader should reach out at that distance.....another area where the Deer may be coming out is to the far left corner of the woods on the left side of the light-blue dots just below the house.....if Your in the middle of that tree line You'll have a shot at a Deer from both sides?Take a limb and lean it up against a large tree and lean a few branches on the larger limb to hide your body line,cedar tree branches work even better since they stay green all year long.

Watch behind that line of tree's because the Deer could very well be slipping in behind those tree's to get out into the Alfalfa Field?
