Are you Kidding Me?

Nik Wallenda, you know, of the "Flying Wallendas,  says he is going to cross Niagara Falls on a tightrope! An 1800 foot walk on a two inch steel cable that he says will take him 30-40 minutes.  NY Legislature and Canadian Parks officials have approved the stunt, which he plans for June 15th.   Since I get dizzy on the second rung of a step ladder,  this seems quite, um, a daunting undertaking, to say the least.
