Kidney transplant recipient Gordon Nahas, 68, from Ellicott City, goes through rappelling training, led by Justin Britcher, left, from Hamilton, and Caleb Vesely, from Flagstaff, AZ, on the 24th floor of the Legg Mason Tower in the Harbor East area of Baltimore Saturday, June 19, 2010. Participants who raised over $1,000 for the National Kidney Foundation of Maryland were eligible to repel down the skyscraper, from the 23rd-floor balcony to the fourth-floor balcony.

Here’s the big jump.

After getting passed the first ledge, Kidney transplant recipient Gordon Nahas, 68, from Ellicott City, yelled up to the rope handlers on the 23rd-floor balcony Legg Mason Tower, “This is a piece of cake!”

Greg Jacobson, 30, from Ellicott City, is next.

Watch out for that first step! Greg Jacobson, from Ellicott City, goes head over heels on his way down the Legg Mason Tower Saturday, June 19, 2010. Sight safety supervisor Brian Dickerson, from Houston, TX, and Zeb Severson, from Aberdeen (black shirt), keep Jacobson steady while regaining his composure. All this drama, twenty-three stories in the air, is for the National Kidney Foundation. The thirty-year-old, who serves on the NKF of Maryland board, has kidney disease in his family. His mother, Cindy, of Timonium is a transplant recipient. Dickerson was joined by several dare devils who raised over $1,000 for the National Kidney Foundation of Maryland.
