In Dagestan one may find such a wonder - a shaft-sinking and tunnelling complex Robbins (USA) that overcame 5 km in the mountains?! It used to be a diversion tunnel 5,2 km long from the dam to the station. Water went
through the generator producing electricity. It was done for elevation changes for bigger station power. The first machine of such type in Russia was exactly here, at Irganaiskaya hydrostation.
There is an amazing place in the very centre of Russia, the Nizhegorodsk region. On the maps it is called the Krasnooktyabrsky district but the locals call it Misharistan. It's the land so much different from all Russia. Misharistan villages are huge, clean, with houses of good quality. Probably this district is the only one in the region from where young people do not go to big cities. If it is compared to neighbouring villages where Russians live, the last one are not the gainers. Misharistan dwellers carefully keep their traditions. You
notice it while talking to them or in their kitchens. And the Tatars cook perfectly! Nobody has ever left them being hungry. Despite the actions of the Soviet authorities aimed at eradication of their religion in the country the local Tatars managed to preserve wooden mosques - unique 200 years' monuments. Not less respectfully they treat ancient Russian traditions. Thus, while meetings or feasts, they have samovars on their tables and drink tea from saucers after the ancient Russian manner.
