The transiberian express starting in Moscow and ending 6 days later in Vladivostok has inspired many over the years. I have to say it’s on my list but considering the journey time may have to wait.
In the meantime I will have to make do with my own little piece of Siberia, my cat.
This is slightly related as he is a Siberian hypoallergenic long haired breed. His paws have little tufts of fur which he has to enable him to walk long distances on the snow.
