I have 360 acres of perfectly flat land. Its a square, so its 1,200y sides, with a 1,800y diagonal. Only problem is you cant see very far because its so flat. There isnt really any high ground. Its all within 3-4 feet of elevation. I was thinking of building a tower, but dont want to spend several thousand just yet. Just a 1 lane range for me to practice on. Anyone have any ideas?
