I know, "DUH! It's at range 2 on the ruler!"
No no...
So what if I'm shooting at something and it literally falls on the line of "Range 1." Let's say half of it's base is on range 1, but half of its base is on range 2. Does that mean I'm firing at range one and do not have a shot at him even though technically... he can fall under range 2? I have a feeling that it's "Closest corner to closest corner period," and nothing beyond closest corner counts.
