Harold knelt on the floor, smoothing out a soiled sheet of paper. In the center was a small circle, labeled in Harold's sloppy handwriting "Earth." An arrow showed the direction of the Earth's motion around the Sun. Outside this was a larger circle labeled "Orbit of Moon." A spiral reached out from the Earth to intersect the Moon's orbit.
"Had the darnedest time drawing this," Harold said. "Got it out of an astronomy book. Let's Look at the Stars by someone. Thirty-five cents. Let's see now."

"Harold, another thing," said Orville. "I weigh around one ninety-five. Won't that take a lot of extra gas?"
"Nope. Doesn't matter if you weigh a ton. According to my counter-grav principle—"

"Why, I have some oxygen. That welding place in back of the garage where I work—got a tank off them. Had to pay cash, but I can turn in the empty when we get back."
"You sure one tank'll be enough?"
