"Engineering marvel" or "colossal eyesore" or scariest tourist attraction in the United States?

The Grand Canyon Skywalk is supposed to help the finances of the Hualapai Indian Tribe, but even assuming lots of people want to walk on a gigantic glass walkway incomprehensibly jutting out over the deep canyon, there are many problems with this:

[Some] in the tribe have been critical of what they say is the development's lack of sustainability, pointing out that water used here is trucked in over miles of unpaved, rutted roads, and that there is no sewer, trash, telephone or electrical service. The airport, which is expanding, operates on diesel generators....

Tribal officials admit it will be difficult to operate a full-service resort without upgrading infrastructure and finding a local source of water. Hualapai officials said last week that they were considering taking water from the Colorado River.

Pumping water up nearly a vertical mile from the river to the rim of the canyon could be fraught with financial and legal challenges. Joseph Feller, who teaches water law at Arizona State University, says no tribe has ever taken water from the Colorado without first negotiating with the federal government.

It sounds like a disaster all around.

Here in Madison, we have a building with a beautiful, dramatic, long glass stairway:



The glass is even frosted, so they're not encouraging you to stare down, and I know a lot of people who are afraid to walk on it.
