Niagara Falls is bracing for record crowds descending on the city this week to watch tightrope walker Nik Wallenda cross the falls on Friday.
Hotel rooms are almost sold out, and GO is running a special train from Toronto.
As many as 120,000 people are expected to jostle for a spot on the Canadian side of Niagara Falls to watch the 33-year-old daredevil make the 550-metre walk.
The last time anyone crossed the falls on a tightrope was 150 years ago.
"We're extremely excited, " said Tony Williams of Niagara Falls Tourism. "It is giving us worldwide attention, which obviously any destination would appreciate."
Niagara Falls Police Chief Douglas Kane says security fences will go up Wednesday and roads will close several hours ahead of the walk.
"The only thing that would stop this event at this point would be lightning," said Kane.
There are still some last-minute glitches to work out, however.
Wallenda's team has been scrambling to get the tightrope stretched across the falls.
Promoter Winston Simone, however, says "the only thing worse than having these problems is not having these problems, because the event was turned down."
Wallenda is scheduled to make his attempt on Friday night.
