Less important people, workmen and others, traveled by interconnecting ice-exploration bores, still easier way to get lost. If anybody carried an inertial pathfinder in his luggage, he could have located site—but security was tight. One did so and had accident with p-suit; his effects were returned to L-City and his pathfinder read what it should—i.e., what we wanted it to read, for I made hurried trip out with number-three arm along. You can reseal one without a trace if you do it in nitrogen atmosphere—I wore an oxygen mask at slight overpressure. No huhu.
