So when we went to Russia the only way that they would let us in is basically if we follow, we were part of a tour guide in a tour group. So make sure that you check visas and passports and everything and all that kind of information early and so you know what you're supposed to be doing.
Don't buy warm clothes in your home country, if you go to Russia, because in Russia clothes made special for Russian winter, and winter sometimes it's not pleasant, it's really cold, but you can see sunshine too. Sometimes warm days have, but winter time was so cold, and try to buy hat, shoes, and jacket, and coat in Russia. Yeah, you not will regret.
