Click on the link for video. You can say what you want about Dubai, but this is impressive.

I hope it's too big to fall.

It's solid "continuous pour" concrete - a construction system pioneered by the now-second tallest building in the world - the CN Tower in Toronto Ontario.

It's all in the eye of the beholder, and I guess now we know what's in your eye.

Chicago has some of the greatest architecture on earth - When my wife and I visited there a few years ago, we did an impromptu architectural tour of the loop and the surrounding area. I had never paid that much attention to architectural styles, so didn't know much before we started, but learned a lot on that trip. I would say Skidmore should be very proud of their work.

We went on the boat tour as an opening introduction to the architecture, and then used a book on Chicago architecture that we bought before the trip. It was a great tour - they really did an excellent job. We were there for Memorial Day weekend in 2005 or 2006 - Had a wonderful time - I think it is probably my second favorite city (how appropriate!) after Washington, DC.

It was great - The views of the city from the river are fantastic - The different perspective from being on the ground gives you a totally different appreciation for how the architects envisioned the buildings and the way they look together. I would do it again in a flash. I have to go back and find the photos I took as we went along - the way the buildings appear against each other is as interesting as each building is by itself.

The Chicago River???? Is it a walking tour?

I haven't been there since the mid-sixties, Sooz. At the time it was not one of the major tourist attractions. In fact, didn't it actually catch fie one time.
