 In telling the story about potentially traveling to Oktoberfest, what is Simon most skeptical of?
When Simon continued to say nothing she ventured, "Time travel is impossible." It's my contention that within a century or so man will have solved the problems of immortality and eternal youth, and it's also my suspicion that he will eventually be able to travel in time.

The Oktoberfest is one whale of a wingding." You could be a four-armed space traveler from Mars, and you still wouldn't be conspicuous at the Oktoberfest .
