They've got a glass floor at the CN Tower in Toronto too - it's pretty badass.

When I was there, one of the chicks that was with us walked out onto it without looking down, not realizing that the floor was clear. Somebody told her to look down, and seeing herself suspended 1000 feet above the ground, she completely freaked. Leaped up in the air, ran over to a pillar and hugged it, and cried like a little bitch until the elevator came. Total attention whoring, but funny nonetheless.
