Here's a quote from the Seattle Met article:
Nelson, who didn’t become a firefighter until he was 44, trained for the department’s qualifying endurance test by hauling 100-pound sandbags up Laurelhurst’s cruelest hills. Right up until the day he tries to conquer the Columbia Tower, he’ll be scaling stairs at Husky Stadium—with an air mask and 60 pounds of gear instead of sandbags.
Unbelievable! He's just over halfway to reaching his funding goal. You can help him out by making a donation at his web site.
