As far as I know a mile = a mile in Texas and in D.C. and I fail to understand the connection you are trying to make. I have never heard anyone else try to make a geographic connection between Dallas/Ft Worth and Ft Hood.
In relative terms, as regards the significance of distance, would you say that a dead-center bulls-eye shot on a target at 3 yards is better, or about the same, as a shot placed a couple of inches from the center at 20 yards?
