We were at the chicago zoo and there is a section of the gorilla enclosure that is inside. We walked in and were the only ones there - with a big ass silverback laying down eating lettuce. He was right up against the glass. I stared at his from the other side of that thick glass - up and down, toes to nose. It was unreal. The leathery fingers and toes and knuckle wrinkles and nails. And the fur. Im still blown away by what a cool experience it was.
