... I would not recommend anybody to travel Russia on your own if you don't know the rituals of this country.
What rituals?
Travelling in the Russian Federation is as easy as travelling anywhere. Just travel from A to B. Buy your petrol. Buy your food. Look for a hotel or a place to put your tent.
Travelling on your own is nothing special. Even in Russia. I did it twice: a piece of cake.
I react here as warnings not to go to a country come usually from people who stay at home or take the more touristic places/countries. You are the first 'experienced' traveler who scares would-be-travelers-to-Russia off. I'm amazed.
And if you don't speak the language, you need a lot of luck.
You can travel in any country also if you don't speak the language. That counts for Russia too. Just have an open mind, use gestures and common sense.
Of course I will advise anyone having plans to travel there to learn -some- russian before. That effort will pay back.
