A short stop by Riga. Moscow at 10 PM. Like Champollion we read panels letters one by one and we finally find our way to the AeroExpress, a rapid train from the airport to downtown. Then we catch the metro, an additional challenge. But we make it. The real issue is more trivial : crossing the street, a six lines highway ! We find our street without any problem, but understanding how street numbers work is a new treasure hunt ! But we will make it again, and we are kind of proud !
