I'd call it practice, but the people of Baltimore were wowed by it!   Nik Wallenda completed a walk across the Inner Harbor on Wednesday, at times dropping to a knee and pumping his fist, to excite the crowd.  I call it practice and you will too, after seeing the video.  In my opinion, his real test will be on June 15th, when Nik attempts to cross Niagara Falls.  Here's how it's going to work..... Nik Wallenda and his crew will set up two cranes...one on each side of the Falls....American and Canadian.  Run between those two cranes will be a custom made wire that Nik will cross the Falls on.  The stunt will take up to 40 minutes to complete and Nik will be working from 60 meters (close to 197 feet)  above land.  By the way, the whole thing will be broadcast live on the Discovery Channel.
