We have had no internet for the past 36 hours so I haven't been able to update at all. The main news is that Channel 4 have pulled out of the expedition. The Russian Government apparently refused to grant a visa to the film crew. The area of the expedition is perilously close to Chechnya and other trouble spots for their liking, and they are afraid of an anti-Russian documentary being made by the folks in what is euphemistically described as the free world.
So we are on our own.
