I've visited about third of Russian territory and could remember it without any maps
Here in the USA if/when the kids go to a really good school they learn at the age of 12 in what we call 7th Grade (the 7th year of schooling beyond "pre-school") all the geographies of all the world.
It starts with the USA and all 50 states. Everyone needs to learn the major product of that state plus the state capitol, if they don't already know them.
Then the teachers move on, to the other countries.
North America (the rest of it) is usually first since it is closest.
Then South America.
Then Europe.
Then Asia.
Then Africa.
Then the Pacific island nations and Antarctica.
This all involves a lot of memorization. The kids need to use mnemonics to do it. But they get a good sense of where the 196 nations (plus or minus) are located, what their capital is, and what they produce.
Many of these nations have changed since I was a kid. But I think I know most of them still.
Russia has not changed but Soviet Asia has. But I know most of them as well now.
Russia is and always has been a very big place. I think of it as like a combination of Canada, the USA, and Mexico if all 3 were combined.
Almost infinite natural resources in Russia -- oil, gold, other precious metals, precious rare earth metals, timber, clean water (except around Chernobyl), fresh air.
I am surprised that there is not more development of the Russian wilderness. So much food could be grown there to feed the starving Africans!
I suppose that the past 100 years of cold war and communism has detracted from further development. Stalin was a plague upon Russia for a long time.
I hope that Putin does not get distracted by a new cold war. But if he does it is due to the CIA and to Obama's blunders in a job that was too big for him to do right, internationally.
The only hope for the world right now is that Trump and Putin get along and don't go further road of cold war.
