One of the great things about Las Vegas is that it’s a people-watchers’ paradise.  Consider this a field report.

• Vegas is decidedly heterosexual.  There weren’t many singles, and the male-female pairs strongly predominated.  We saw perhaps two lesbian couples (they were holding hands), and no two-male pairs that suggested anything other than hetero friendships.  The sexuality is almost exclusively oriented in hetero fashion — I never once saw an ad for a male strip club — and even the high-profile male revue shows will bar admittance to men.
• Young Asian males overwhelmingly dress in trendy metrosexual fashion, even when they’re married.  
• Buff men flaunt it.  So do toned women.  No one else seems to care.
• There are many more tattooed men and women in Vegas than in West Michigan.
• Many of the white tourists appeared to be from Eastern Europe, judging by the sounds of their language.  There didn’t appear to be many Hispanic tourists.
• People who wear non-standard clothing styles usually pull off some funky combinations if they look and act confident.
• Most gamblers don’t bother to check pay schedules — they’ll merrily sit playing 6/5 bonus poker with nary a thought about the house edge.
• There didn’t appear to be many people who visited the casinos alone.
• Never underestimate the brainlessness of a herd, especially when it’s comprised of youngsters.
• The gaming professionals in Vegas know their jobs well.
• You know how to tell a first-time visitor?  They’re the ones with cameras.  On second and subsequent trips to Sin City, the glitter fades.
• Many people seem to lack a fundamental sense of space — they walk and orient themselves as if no other humans were around, thus presenting barriers to navigation that require fancy footwork to ameliorate.
