Nik Wallendra is walking blindfolded between Chicago skyscrapers on a tightrope more than 50 stories high. I'm going to try to watch it.

And I thought riding the glass elevator to the top of the Sears Tower in Chicago was scary.

I was flipping the channels and caught the show but he hadn't started yet, so I changed the channel and forgot about it.
