The Costa Rica Hilton soared one hundred and six floors upward from its flat, four-story base. On the roof of this lower structure were tennis courts, swimming pools, solariums, racetracks, merry-go-rounds (which simultaneously served as roulette wheels), and shooting galleries where you could fire at absolutely anyone you liked-in effigy-provided you put in your order twenty-four hours in advance, and there were concert amphitheaters equipped with tear gas sprinklers in case the audience got out of hand. I was given a room on the hundredth floor; from it I could see only the top of the bluish brown cloud of smog that coiled about the city. Some of the hotel furnishings puzzled me-the ten-foot crowbar propped up in a corner of the jade and jasper bathroom, for example, or the khaki camouflage cape in the closet, or the sack of hardtack under the bed. Over the tub, next to the towels, hung an enormous spool of standard Alpine rope, and on the door was a card which I first noticed when I went to triple-lock the super-yale. It read: "This Room Guaranteed BOMB-FREE. From the Management."

It is common knowledge that there are two kinds of scholar these days: the stationary and the peripatetic. The stationaries pursue their studies in the traditional way, while their restless colleagues participate in every sort of international seminar and symposium imaginable. The scholar of this second type may be readily identified: in his lapel he wears a card bearing his name, rank and home university, in his pocket sticks a flight schedule of arrivals and departures, and the buckle on his belt-as well as the snaps on his briefcase-are plastic, never metal, so as not to trigger unnecessarily the alarms of the airport scanners that search boarding passengers for weapons. Our peripatetic scholar keeps up with the literature of his field by studying in buses, waiting rooms, planes and hotel bars. Since I was-naturally enough-unacquainted with many of the recent customs of Earth, I set off alarms in the airports of Bangkok, Athens and Costa Rica itself, having six amalgam fillings in my mouth.
