“The mind,” Hedrick Smith wrote in The Russians, “is little equipped to comprehend a nation that encompasses 11 time zones.” Well, okay (and anyway, the Russians have lopped off a couple of time zones, leaving a mere 9). We can’t quite comprehend it, but we can and do very much appreciate it. We design journeys that roam across all those time zones, from the august wonders of St. Petersburg to the remote Kamchatka Peninsula.
