I found Lenin's mausoleum fascinating. It was incredible to me, as an historian, to see such a famous (or infamous) figure lying there, as if merely asleep. I was amazed, too, to see that Lenin had red hair and a red beard. I had only seen black-and-white photos of him before.
When I lived in Moscow, my wife and I walked through Red Square practically every day. I remember commenting to her that Red Square is the perfect symbol of the Russian soul: there stands one of the most beautiful churches in all of Christendom (St. Basil's - now a museum) and nearby the tomb of one of Satan's most devoted servants.
My wife, a Russian native, remarked that many Russians believe that their land will never be blessed and prosperous until Lenin's body is removed from Red Square and buried somewhere else.
I love Red Square. It is a place of fairy tale-like beauty, power, and mystery.
It is also a tourist Mecca. I think I heard as much Italian, German, Japanese, and English spoken there as I did Russian.
Lenin's body is a definite draw. All those vendors in the little mobile shops selling beer, Otvortka, and kolbasa might be upset if it is removed and their trade declines.
