My source was Emporis and I haven't looked at the stats you listed in a while. It's certainly possible that with all of the construction going on, that they have dropped out of the ranking I listed. Oh and by the way, that stat was based on roof height.
Anyway my point was not to put out some crazy number regarding Houston, it was to make the point that we've got some pretty damn tall buildings. Geeez, even with the numbers you posted we're not doing to bad, so you reiterated my point for me.
Do me a favor, if I've put out some incorrect info, don't be sarcastic about it. Thanks.
