I'm sure I'll get up to St Petersburg for a weekend eventually. Only a few hours away by train, I believe.
I'm re-reading Nabokov just now...getting a bit fed up with him, actually. I find his descriptions of women rather juvenile.
I'm a Solzhenitsyn fan, though I can never manage more than a couple chapters at a time, as the subject matter is so disturbing. Dostoyevsky is great, though. I've been re-reading C&P since I was a teenager; I often return to themes of guilt in literature.
