I can't remember now which Wallenda it was exactly but on Independence Day in the mid to late-90's, I and my family saw either Nik's father or one of his uncles (it may have even been Nik) walk a slack wire across the stadium at Liberty University. As he walked, he preached a pretty good sermon, clearly without notes. :-) Either task requires a good amount of concentration and, in this case, both were done well.
By the way, the celebration was entirely without cost, requiring only advance registration for planning. I did make a decent donation and when I explained my personal convictions, no further solicitation was made.
