JUBAL HAD A MISERABLE TRIP.  The taxi was automatic and it did just what he expected of machinery, developed trouble in the air and homed for maintenance instead of carrying out its orders.  Jubal wound up in New York, farther from where he wanted to be than when he started.  There he found that he could make better time by commercial schedule than he could by any charter available.  So he arrived hours later than he expected to, having spent the time cooped up with strangers (which he detested) and watching a stereo tank (which he detested only slightly less).
