Freki's senses are acute enough to tell before he fires, that the tarantula has been dead for months*.  Its withered exoskeletal husk is held in place by a framework of webs.<br/><br/>Beyond the dead tarantula, the hills roll down to the airport, the light rail tracks and highways leading the way to miles of runways, parking lots and access roads that lead to the huge terminals.<br/><br/>All the terrain leading to the airport is covered in a solid sheet of the same webs that trapped the tarantula.<br/><br/>Then Freki notices what was enough to scare the Gensects.<br/><br/>First, the bite marks that show where something stabbed into the tarantula and sucked it as dry as poking a straw into a capri-sun drink pouch.<br/><br/>Next, the hole in the wall of the terminal, where something broke in.  Something big enough to dwarf the tarantula and use an aiport terminal as a lair.<br/><br/>*you may choose not to fire and wake up the neighbors, if you want.
