Russia is a fascinating country that is currently the biggest in the world. It stretches ACROSS (almost) two continents and covers nine time zones. Russian metropolitan cities boast of famous museums and breathtaking architecture. The biggest(most important) city is its capital, Moscow, and the second (in importance) is St.Petersburg, the former north(ern) capital founded by Peter the Great.
If you visit Moscow, you should first of all visit the Red Square, the heart of Russia. Around it, there are several museums, two famous churches,(St.Basil's Casthedral) Lenin's mausoleum, and the first Russian shopping mall, the GUM.
Here is some advice for foreigners who decide to visit Russia.
First of all, try to learn several English (Russian?) words. Certainly, there are lots of people who know Englis(speak foreign languages) but there is also a big percentage of people who do not know (a word of) English.
Secondly, make photocopies of your documents, which should be carried (and carry them ...at all times)) with you all the time (to avoid being a victim of a pickpocket). There are a lot of pickpockets and you might become their victim. That's why it is advisable to leave documents in a/at your hotel. A Big warning! Do carry a photocopied passport with you all the time as THE Police in Russia are inclined (will want to/are on the lookout for foreign-looking people)) to check your passport and other documents.
Avoid drinking tap water.(It may disagree with your stomach) It is not correctly cleaned and can lead to severe diseases (Может, не стоит так пугать? Все-таки не Африка) . Don't flaunt (your thick wallet in public )that you have money in public places. Avoid walking in parks and in deserted streets alone after (dark) 11 P.M. That will reduce your chance of getting robbed. Don't exchange money in the streets; do it only in licensed banks. Do not use unlicensed taxis because you may be ripped off. If you stay at your friends', according to the law, they should/must register you in/at/with the Federal Migration service/Office within the first seven days AFTER your arrival. It will be a good idea to always have a Russian friend with you to engage in negotiations with waiters, souvenir vendors, taxi-drivers etc, because otherwise you'd be charged times more as a foreigner.
At last/finally, there is a lot of places for sightseeing. It would be more convenient, interesting/enlightening, cheap/money-saving and altogether safe if you took a sightseeing tour around the Russian cities that you have an/the intention to visit.

Матка курка, матка шпек, нихт шиссен! And no thing more in English soрри... Читается зело внятно и ясно - tipical standart инглиш (читай - весьма грамотный подстрочник) . Но слегонца нафталином попахивает.
