I thought we could just take the train from Erenhot back to Ulaanbaatar, but no! We had to hire a jeep. The five-person jeep carried all nine of us--with me holding the front passenger door closed with a strap through two border crossings and one health inspection stop. After some miscommunications and the purchase of 'VIP' train tickets (a.k.a. a small bribe) Miki and I made it onto the Zamin-Uud to UB train. On the train we shared our cabin with a Mongolian business man who was both a great Mongolian teacher (he spoke slowly and clearly with a basic vocabulary so I could understand) and very generous.
Although it was a fascinating place, with signs in Chinese and Mongolian (Cyrillic and the older script) and Mongolians speaking with an accent even I could hear, I was happy to get back home to UB and prepare for my trip to the countryside (photos to be posted soon).
