Ural in Russia is a various and interesting place. Part 1 I was born in Magnitogorsk city. Magnitogorsk is at south Ural at middle Russia. I love Ural because it is various places such as plains, forests, mountains. You can meet old road through forest made of stone. Also you can meet 1909 yer old hydroelectric power station (who's called Porogi (Пороги)) on the river who's called Big Satka (Большая Сатка). And of cause you can find old metallurgic manufacturing, but they did not work today. And more interesting places.
