I was in Ulaan Baatar for about 36 hours, fried from having taken the late train from the south (left southern Mongolia at 1:00 am, arrived in UB at 8:00 AM), and I had the shits all night and so got no sleep (from a US candy bar, of all things - or so that's the best I can guess). Nothing too big to report, other than after my Mongolian train experience, I decided to fly back to Beijing rather than take the train. Another factor playing in my decision to not take the train south, which I've been looking forward to for months, is that if I had taken the train (based on the train schedule), I would have had five more days in UB and only one in Beijing before heading to Fiji. I wanted more time in Beijing, so fly I did.
