Yes, I did. I suppose you recently visited Moscow with your wife and also visited Lenin's mausoleum? So, how is it now?
I was there in 1969, when I was in 4th grade, I was 10 years old. My mother took me there during one of our trips to Moscow, because for a soviet citizen it was a must to visit it. I was never in the mausoleum before, but my mother decided that I was old enough for this and that it will be something to report in one of the classes when back to school in fall.
We came to the Alexandov garden very early in the morning to get into line. A line of visitors was formed in Alexandrov garden. You had to wait in line to get into the Lenin's mausoleum. We came several hours earlier than the opening hour. There was a huge crowd of people there, but unlike any other line in Soviet era, this one was organized and pretty civilized. While we waited for the mausoleum to open, I had lots of fun playing with other kids from the crowd. Then the line started to move steady and within an hour we got to the Red Square and then to the mausoleum.
Frankly speaking, I was not very enthusiastic to see a dead person in a coffin. Honestly, I did not want to do it AT ALL. But I suppose, it was "an honor", not many kids from my school happen to have this experience.
When we got inside, I was so scared and so nervous already, that I was having involuntary muscle contractions in my arms, they were shaking. It was cool and semi-dark inside; in every corner a soldier was standing at the wall on the crowd way. We went through a small room in a semi-circle. In the middle of the room there was a podium with Lenin's corpse. I gave it only a very short glance, I was not able to look at this longer. I was looking under my feet all the way. It took us probably less than a minute to pass the way, but it seemed like an eternity for me.
When we got out of this place into a sunny day, it was a complete relief for me. Only later I confessed to my mother what a torture it was for me. She apologized and said that she considered that it might have been beneficiary for me because then I had to tell about it at school. She also said that it was not a real dead body of Lenin, but likely a preserved with formalin stuffed doll.
It was my only time of visiting the Lenin's mausoleum. During my numerous visits to Moscow even a thought about it never came to me.
