Taking a break from my work to walk along the city wall. If the cows every become rebellious and try to take the city we are well prepared.
I was listening to a sf story from 1939 when I heard and unintentionaly humorous line. The story takes place on a habitable planet Venus and the explorers have befriended the natives. As they are flying toward a city, the Captain points at the city wall and asks, “What are those things that look like giant ray guns?” Um….. So this picture is the one which came to mind.
