SEATTLE -- Firefighters from around the country took to the stairs of Seattle's Columbia Center in full gear for a cause: to raise money and awareness for the Leukemia and Lymphoma Society.

Approximately 2,000 firefighters climbed the 69 floors to the top observation deck of the building, with 50-plus pounds of gear.

The firefighters have raised $2 million for the Leukemia and Lymphoma Society so far, with donations accepted through the end of the month.
