Martin Park swings himself with a fearless jump onto the steep sloping roof. He just wanted to quickly give the windows a wipe on the outside. One hand holds on to the window frame while the other wipes the glass. One foot feels for a grip, the other slips. His breathing stops – no. “Pretty slippy up here” he states calmly and maneouvers himself into position again. It’s an advantage that free-climbing is one of his hobbies. And maybe also that he can’t see the chasm below him… for Martin Park is blind.
