Hey Stuart and Oli,
when will you arrive Mongolia? We are a couple and now in Omsk.
I saw that you will go to Baku and take the ferry?
We have done this way bevore 3 Weeks.
Consider:
the ferry is not really an awesome ferry.
You must use your own straps to fix the motorbikes.
The ferry drives ~39hours.
Near the ticket office (on the main street to north, next crossover) is a supermarket to get some water and food. The food on the ferry is not good.
Do you want go over gerogia?
At the Azerbaijan border we must plead for a longer permission for our motorbikes, but they where helpful and gave us some fruits and a meal.
(4hours for this border)
The Kz Border in Aktau is horrible.
We needed 6 hours to get all stamps for a documet, to give/leave "this" at the gate!
Everything was an experience... this is a journey
