Niagara Falls, ON (WBEN) He's been walking tightropes for 50 years, and Jay Cochrane will be spending his summer walking over a part of Niagara Falls, Ontario. He'll be walking each night for 12 weeks from Niagara Fallsview Hilton Hotel's north tower to the top of the Skylon Tower, 600 feet in the air.

Cochrane says the goal is to help raise money for a pair of children's charities, the Boys and Girls Club and Tender Wishes, which helps terminally ill children have their wishes granted. "I always have a goal, and I try to surpass it. Instead of setting a limit, I'd rather be able to say I raised more than I expected," explains Cochrane in not mentioning how much he'd like to raise. The walks are free, as are posters, and spectators can give donations. They can also buy DVDs of his performances, the proceeds of which will go to charities.

How many could watch? "It's hard to say how many will be watching, but there's usually 25,000 people here a night, as many as 50,000," says Cochrane. This will be the longest and highest combination walk numerous times, with 81 scheduled walks 600 feet high, and walking across 1,300 feet.

This will likely be the last time we see Cochrane perform, as he plans on retiring next year.
