So no spoilers here, but eventually Sheldon (rather, his voice) states that four state capitals don't lie on the American Interstate System. Being the trivia buffs we are, we set about guessing which ones and then hit up ole Wikipedia to check our answers. I even found interstate trivia on the Federal Highway Administration website. ALERT: SHELDON WAS WRONG. Apparently, five capitals aren't connected to an interstate. Which ones, you might ask?
2. Juneau, Alaska: Poor Alaska. Even Honolulu got its own interstate. I personally think it would be a good idea to connect Juneau and Anchorage with an interstate.
3. Carson City, Nevada: My brother-in-law claimed that Reno was the state capital. Not so. But Reno is on I-80.
4. Jefferson City, Missouri: No, St. Louis is not the capital of Missouri. J City (my new nickname) is just kind of hanging out by itself.
5. Pierre, South Dakota: Surprisingly, two interstates intersect in Sioux Falls but neither goes that close to Pierre. Poor Pierre, so lonely. Hell, even Sturgis is closer to I-90.
