I mean.... really it's just plain ol' common sense. Bragging rights.... schmagging rights.... height is height and I for one am with Kevin on this one. I don't care if it's just a lollipop sticking on top.... if it stands at 700' then it stands at 700'.
You can include other criteria if you want, but really, who's gonna care? It's still gonna look mighty impressive to see that building stand that tall in a very near proximity to I-35. I'm all happy for Austin and can't wait for it to go up.
That being said, your arms may not be an indicator of how tall you are, but they are an indicator of how long your wingspan is... they use that criteria in basketball all the time... so obviously it does matter!
