Everywhere in South Lake Union, you see guys wearing day-glo clothes while tearing shit down. And it's fun to watch. In fact, it's strangely peaceful.

Today, I watched some dude in a construction vehicle I've never seen before (but which vaguely resembled the bad-ass machine that Sigourney Weaver used to fight the Alien Mother) topple a brick wall.

It appeals to the 6-year-old in me, the kid who'd build toy block towers and then kick them to pieces. To the kid who'd douse plastic army men with kerosene and set them afire.

But it really appeals to the urban man I've become. All the great cities in the world have serious population density. So maybe, just maybe, this means our city is moving into puberty.
