The grin never left Agnes Helmink's face – not even when the senior stepped off the edge of a 22-storey building in downtown Saskatoon.

The 79-year-old rappelled down the side of Carlton Tower on 5th Avenue to raise money for Camp Easter Seal.

"When I celebrated my 75th I was in Tel Aviv, so I figured before I reached my next decade I should do something exciting again," she said.

Helmink has a grandson who benefits from Camp Easter Seal. She raised more than $2,400 in pledges.

She wasn't alone. The Easter Seals Drop Zone attracted dozens of brave-hearted climbers who all raised pledges for the charity. This year, the participants donned super hero costumes for their trips down the building.
