"The _Oktoberfest_," he repeated. "The greatest festival the world has ever seen, the carnival, _feria_, _fiesta_ to beat them all. Every year it's held in Munich. Makes the New Orleans Mardi gras look like a quilting party." He began to swing into the spirit of his description. "It originally started in celebration of the wedding of some local prince a century and a half ago and the Bavarians had such a bang-up time they've been holding it every year since. The Munich breweries do up a special beer, _Marzenbraeu_ they call it, and each brewery opens a tremendous tent on the fair grounds which will hold five thousand customers apiece. Millions of liters of beer are put away, hundreds of thousands of barbecued chickens, a small herd of oxen are roasted whole over spits, millions of pair of _weisswurst_, a very special sausage, millions upon millions of pretzels--" "All right," Simon said. "We'll accept it. The _Oktoberfest_ is one whale of a wingding." * * * * * "Well," the old boy pursued, into his subject now, "that's where they'd be, places like the _Oktoberfest_. For one thing, a time traveler wouldn't be conspicuous. At a festival like this somebody with a strange accent, or who didn't know exactly how to wear his clothes correctly, or was off the ordinary in any of a dozen other ways, wouldn't be noticed. You could be a four-armed space traveler from Mars, and you still wouldn't be conspicuous at the _Oktoberfest_. People would figure they had D.T.'s." "But why would a time traveler want to go to a--" Betty began. "Why not! What better opportunity to study a people than when they are in their cups? If _you_ could go back a few thousand years, the things you would wish to see would be a Roman Triumph, perhaps the Rites of Dionysus, or one of Alexander's orgies. You wouldn't want to wander up and down the streets of, say, Athens while nothing was going on, particularly when you might be revealed as a suspicious character not being able to speak the language, not knowing how to wear the clothes and not familiar with the city's layout." He took a deep breath. "No ma'am, you'd have to stick to some great event, both for the sake of actual interest and for protection against being unmasked." The old boy wound it up. "Well, that's the story. What are your rates? The _Oktoberfest_ starts on Friday and continues for sixteen days. You can take the plane to Munich, spend a week there and--" Simon was shaking his head. "Not interested." As soon as Betty had got her jaw back into place, she glared unbelievingly at him. Mr. Oyster was taken aback himself. "See here, young man, I realize this isn't an ordinary assignment, however, as I said, I am willing to risk a considerable portion of my fortune--" "Sorry," Simon said. "Can't be done."
