Regarding the ongoing debate:
What constitutes "riff raff" is, of course, in the eyes of the beholder. Here are some of the people I've met in Amtrak coaches and lounge cars during the past year or two:
-- a trio of tattoo artists traveling to a tattoo convention
-- a lesbian dance company
-- a 70 year-old ranch hand, who was venturing out of Colorado for the first time in his life
-- a NASA engineer who'd helped develop the Mars Rover
-- a very refined, middle-aged English junkie (think Peter O'Toole)
-- six elderly bluegrass fiddlers
-- a sad woman on her way to the foreclosure of her brother's farm
-- a one-armed biker and his "old lady."
-- a Japanese speed metal band
-- a peaceful family of illegal Mexican immigrants (who were pulled off the train by the INS)
-- two cute Irish nannies, "out to charm America"
-- a stage mother and her "wildly talented" teenage daughter
-- numerous retired employees of various Fallen Flag railroads
-- a group of inner city spelling bee champions
-- two Buddhist monks
-- a woman and her five kids, on the run from an abusive husband/father
-- an Amish farmer
-- two strippers from Kentucky
-- a quartet of South Asian sisters, each wearing a spectacular sari
-- a birthday party clown, in full costume
By contrast, the sleeping car passengers I've traveled with tend to be white, comfortably middle-class suburbanites. The majority are aged between 40 and 70. And many seem to have eerily similar lives -- 16 years at the XYZ corporation, house in the 'burbs, hate the traffic near the new mall, like golf, 2.5 kids in college, wary of big cities, etc.
Are there exceptions? Sure. But you don't find many tattoo artists camping out in an Amtrak sleeper. And, sad to say, the only non-Caucasian in the entire car is usually the attendant.
Granted, not every coach passenger is a living treasure. I've encountered my fair share of Neanderthal frat boys, football bozos, demonic three year-olds, Wall Street morons with cell phones, and drunken off-duty cops.
But while some might dismiss several of the passengers on my opening list as "riff raff," I certainly enjoyed meeting them. They may not be Middle America -- or "normal" -- but I'd ride with them anytime.
