Freaks me out

I freely admit that I am an acrophobe.

I love flying in airplanes, but looking down from tall buildings creeps me out. I went to the top of the Sears Tower in Chicago several years ago and took several minutes to work my way over to the window to look down.

Now the 103rd floor observation deck has glass platforms that make it possible for visitors to step out and peer straight down. The platforms opened July 1.

Thanks, but no thanks.
