_Ed over at Gin and Tacos is collecting tales of travel woe, so I didn't resist adding one, vintage 1986.
If it's a question of helpless travel suffering . . . I remember my friend and I were on an overnight train through Yugoslavia (back when there was such a place) and 5 local workmen piled into the compartment made for 6. And settled in, kicking off their shoes, the fumes from which immediately drove all oxygen from the train, or would have if the window had opened, so maybe the oxygen just died. Even the cheap Russian cigarettes that someone was always smoking, couldn't compete. Propped by the entryway door we at least got the occasional welcome whiff of diesel exhaust, but couldn't even pass into unconsciousness, because the 5 guys only had 4 tickets between them, so somebody had to climb over us and go hide in the bathroom whenever the clairvoyant one thought the ticket taker might be coming.
