NIAGARA FALLS, N.Y. -- Walking a high wire over Niagara Falls isn't only a dicey proposition, it turns out it's pretty pricey, too.
Daredevil Nik Wallenda estimates his history-making, U.S.-to-Canada walk by way of a cable strung over the brink will cost about $1.2 million to $1.3 million.
That includes fabricating and installing the custom steel wire, permits, security, travel, marketing and on and on.
Wallenda says a deal with ABC to televise the event live during prime time will offset some, but not all, of his expenses.
Without a lot of time to find other sponsors, he's been asking the public to help offset costs.
A video on the fundraising website Indiegogo had raised more than $15,300 toward a $50,000 goal by Tuesday.
The walk takes place Friday, June 15.
