1500 feet

So did anyone happen to watch yesterday Nik Wallenda's walk across the Grand Canyon??  I haven't even seen any news coverage of it today but it was one of the most amazing things I have ever seen.  It was covered on the Discovery channel.  He did it without tether or net and my heart was in my throat.   Truly an incredible feat.  I would not even be able to walk to the edge and look down.
