The visas are here. The airplane tickets are in hand. The bags are packed. The grandparents have arrived. We are about as ready as we will ever be.
We don't know anything about potential new son. We don't know if our laptop will work in the region. We don't know if the train is heated or not. We don't know if we will have an extra day in Moscow or not. We don't know much.
I think ignorance is bliss in this situation.
Luckily, we love adventure. Whee!
