The Las Vegas air hit like a hammer when I stepped out of the air-conditioned hotel. I stopped and let a gaggle of Enterprise crewcritters, several Ferengi, two Chewbaccas, and a storm trooper wander past. They were loud, truculent, and appeared to have been sampling Terran alcohol to excess. After a few seconds of semi-coherent argument, they turned and crossed the street more or less as a unit.
