Art museums are cool. Science museums are educational. But if you’re the kind of person who really wants to learn about the city you're visiting -- about its history, its buildings, what it was like when Daniel Day-Lewis fought an epic gang war against Leonardo DiCaprio -- there’s nowhere better than the local city museum. And while, sure, some are nothing more than a collection of old pictures and trinkets, others offer elaborate interactive experiences, live-action historic recreations, and, in one case, the world’s largest No. 2 pencil (!!). Here are nine you shouldn't leave town without visiting.
