By Convention

I saw Mark Duell on Cavuto today. Good Job, Mark! It got me on Flight Aware. Anyhow, one thing I am a pain on is the use of the term border. By convention, it refers to national boundaries. Technically you can refer to any political boundary as a border. However, by convention, state boundaries are referred to as state lines. Also there are county lines, by convention. Or city lines, by convention. You don’t say Denver’s border, you say Denver’s city limits, by convention. :wink: Just an interesting point, Mark.
