This was my first real homewall, and still one of the best. So many friends had so much fun up in that attic. We made many holds of wood and rock, but also bought whatever plastic we could from the local gym Vertical Adventures, the only place to buy grips on Columbus, OH, in those days. It was 24ft (3 sheets) wide and featured 16×8 45-degree overhang screwed directly to the roof trusses. Glad the landlord never noticed. Everything had to fit through a tiny window so all the ply was cut into 4ft widths. Got me hooked, got me strong.
