Visitors to Terrapin Point at the Niagara Falls State Park were aware of the upcoming event.
Tourists were to look at the rushing waters and the rising mist that results at the Falls. And they would occasionally glance at the nearby equipment that crews would use to string the cable.
A helicopter to aid the process had yet to arrive on Tuedsay afternoon.
William Smyers of Buffalo, a freelance photographer, says he is hoping to stake out the best location for a picture on Friday night.
"I think it's a fantastic thing for the area, especially if they continue to market it out correctly and bring in a lot of tourists," Smyers says.
Sally Glasgow of Niagara Falls says she can't wait for the event, but will likely watch it on television.
"We came down and watching him [Nik Wallenda] practice. I watched him three times. He was wonderful. Very personable," Glasgow says, adding that he would walk backward on the practice tightrope would get soaked in the manufactured mist.
Some other tourists from places such as Maryland and Wisconsin said they'll have to leave Niagara Falls before the event -- but will watch the spectacle on Friday night.
