Ha ha! That's exactly the conclusion my husband and I came to. I'm from a hunting family and that's why I also wondered if the structure that my map points to (and that you all have referred to) is a kennel or something for a hunting club? Can any of the locals go check it out? I could but I'm a couple of hours away.
FYI, when you zoom in at maps and stare at things, you can imagine all sorts of interesting stuff...:crazy:
(ETA: I don't really think it's someone with a gun, but I do believe duck blinds are usually lower? If you look at how long the shadows are for the trees, etc., it seems like a tall narrow structure?)
THEY ARE INDEED DUCK BLINDS. ONE EVERY 500 YARDS in that whole area
