I have been through 3. Kathmandu and Ho Chi Minh at least weren't physically dangerous though. Almaty (Kazakhstan) on the other hand...I have written about getting kidnapped at 3am by 2 guys posing as a taxi driver and 'assistant' who threatened to drop me over the adjoining border fence into Kyrgyzstan without any papers if I didn't pay up. It took some bluffing on my part plus $US 70 to get away.
Have any of you seen the site "Sleeping in Airports" It has all the airports graded for tips like good hiding places to snooze and lots of funny anecdotes.
