So What's Nik Wallenda Going to Walk Across Next?

There's something, well, uncomfortable about watching a man walk a tightrope across a 1,500-foot-deep canyon gorge, live on television. Oh, and without a safety net or harness, and only a long pole for balance. And the wind's blowing (unpredictably, and potentially as strong as 30 mph). And a microphone's letting you in on his ongoing prayers to Jesus, and his jokes about not looking down, and his occasional conversation with his dad (who's also miked and back on land).
