Feeley whistled when he gazed upon the massive edifice of stone. It rose three stories easily.
“Yes,” said Warwick. “We built this as a safe haven for whenever the alien walkers attack.”
Feeley nodded solemnly. The alien Farnuche fielded war machines the size of office buildings. They pulped everything beneath their gargantuan feet. Anything that protected people from them had to be massive. Feeley felt that perhaps humanity gained hope with facilities such as this one. He squinted at the winding trench the edifice was built from. He said, “It must have taken a lot of work to build this trench.”
“None at all!” grinned Warwick.
“So how did the trench get here?”
“Why, this isn’t a trench. It’s a foot print!”
