Combating Parkinson's with rock climbing

We were amazed at what we were seeing on a sweltering summer's day, when a group of people with Parkinson's Disease began rock-climbing on the Carderock Cliffs of Maryland. Yes, rock-climbing!

It's all part of their therapy, says Molly Cupka, the no-nonsense instructor and cheerleader for this community of courageous climbers.

She started this program, called UpENDing Parkinsons, as a non-profit twelve years ago.
