What's the Twin Cities' most underrated museum? Partisans of the Museum of Russian Art make a strong case, but others are absolutely religious about their belief that the Bakken Museum—devoted to the whys and hows of electricity—is the best Minneapolis attraction you've never actually been to. Or have you? If not, there's no time like the present: the museum is hosting its annual 10 Best Days of the Bakken event simultaneously with the Aquatennial. The event wraps up on July 22 with a "Sunergy Day" featuring art-making in the Green Energy Art Garden and an informative talk by Rebecca Lundberg from Powerfully Green.
