The unsolicited ads on the Moscow metro for fake MOTs, University diplomas,IDs maintain for me this coutry's mystery. Sure we know that there is a whole lot of corruption but the fake bits of paper ensuring your status as a qualified driver, doctor(!) etc widely available on the black market in the 90s are the thing of the past, right? Not so it seems. Unless those ads on the metro are aimed solely at the very desperate illegal immigrants, like those from Tajikistan who work for pennies and have right to, well, nothing, not unlike Mexicans in the US. Either way this country, unlike any other, presents plenty if opportunities for time travel. And that's what we love it for.))))
