Countdown to Mongolia

I sure hope that I receive my passport and visa back from the Mongolian Embassy by Monday.  Otherwise, CUSO-VSO will have to postpone my travel to Ulaanbaatar.  I am a little nervous.  Of course, there are also tons of details to take care of here before leaving.  I feel so unprepared. 

I keep thinking that I won't have enough room for all of my necessities.  And how do I fit even a few winter garments into one suitcase?  It gets to -50C/F there. Another volunteer advised me to bring plenty of warm clothes.  But how many parkas and thick sweaters does a Southern Californian have or need?  And since I'll be paid a low local wage while I'm there, I won't have money to buy much.  I'm hoping my 2 wool coats and an overabundance of fat reserves will suffice.
