Here is a recent trailcam pic that shows a ghostly object that actually casts a shadow on the ground below it. In the frame prior to this there is nothing to see. In two frames prior there is a doe exiting the frame. Weird!
My guess is that it was a bat that the flash washed out... but then that is a large bat. If you look closely at the pic with the deer exiting the frame there appears to be the same figure in the far background in the upper left. Still pretty eerie! The wife now wants to camp there for the night to try and see it. I told her she was crazy!
Not a bat...moth. Big one, too. The wings and body are the right shape and you can see the antennae. It's close enough to the trail cam to wash out the color while blocking the light from the flash and throwing a shadow to the ground.
Out here in Colorado, and in the units that I haunt, it is a tricky game to figure out how far to pack in on a rifle hunt. You want to get away from the masses that have moved game away from the roads but might want to stay close enough that you are taking advantage of the animals forced movements. There is no universal distance but I like the 1.5 to 4 mile range for day hunts where I am not planning on bivying out. This keeps you in that productive buffer zone where the animals are really...
