I was watching another show, then remembered it was on and switched during the commercials.

I'm glad he succeeded. I was also very glad he wore a security harness; even in the circus, it's great to see what the performers are capable of, and I certainly don't need that danger factor to be entertained (it's the opposite for me actually, wouldn't want anyone to get injured or worse just for a show!).
I went to Niagara Falls a few years ago and it was great to see the area again. I remember taking a walk close to the falls in the evening and at one point I thought it was raining, but it was just water drops from the falls. I could relate a little to what the conditions were for him up there.
