Can't see the range from his house, or from my house, or from any other houses within a 1 mile radius. Nearest visible house is every bit of 1.5 miles away. The range is located on low land, nearest homes are his and mine and one other, all 3 of those are located up on top of the ridge line about 40' above the range area, and several hundred feet through the woods.
The range flag would have to be on top of a VERY TALL pole.
Throw a rock through his window with a small flag attached.
