I know lunar eclipses aren't that uncommon. But you're watching the earth's shadow move quickly across the moon, making a shadow puppet of one space rock on another. That's cool, and it's worth stopping a minute to watch.
But we couldn't watch at home, because our weather has been hit or miss all spring and today was a miss. So I checked the weather, noticed Wisconsin should be nice, and came across Devil's Lake State Park, which sounds kinda metal, and comes billed as having pretty dark skies.
