I worked for a time in an office that rented a room on the territory of NII. There were many typical bodies, which are completely the same on the outside, and the numbering is in the order of construction, that is, behind the second can easily stand the seventeenth.
The main benchmark on the way to work was a poster of the 1970s, telling about the products of NII. He looked horrible, in places rusted to holes, licked by rain and sun, but you won't go by even if you want to.
In general, in the third week of my work in this office, the remnants of the NIH, who lived on one floor of the same building, made a slide and pulled the poster closer to themselves. Greater horror than when I did not understand where to go now, I had never experienced.
