I know that some folks go on vacation and buy up tons of souvenirs. I did not do that on this trip, but in hindsight, there are a few things I wish I had picked up while in Russia.
Many items can be found at the Izmaylovo Market. In case you want some old Soviet memorabilia, this is the place. Me? I wish I had grabbed one of the wooden statues of Grandfather Frost.
If matryoshka dolls are your thing, they had plenty of those too.
Tolkien Bonus: I is for Isengard, a fortress in Gondor. In the Third Age Saruman began to live in Isengard, housing Orcs and building his army until Isengard was destroyed by the Ents.
