The clearest way into the Universe, according to John Muir, is through wilderness. We take a rather flexible view of the wild (and the Universe, for that matter). It's where things grow unchecked. It's a place with no straight lines other than the horizon. It's a world of multiple legs — ur, six, eight — and those of us limited to two can only visit.
You can find the wild almost anywhere. It forces itself up through sidewalks, it intrudes along borders, it worms up walls and clings to fences. You don't even have to search for the wild; if you wait long enough, the wild will come to you.
