There is a scribble of asphalt and meandering ribbons of concrete tangled all over North America in a contiguous line of material that connects each of us to whomever else is also in contact. I sometimes marvel at this, walking from my front door and standing on the asphalt looking down at its grimy blackness, wishing I could rest my ear down on it and hear everything like the Indians in an old western film. The pavement I’m standing on is connected to other pavement, concrete, or steel to almost anywhere I can think of. Certainly everywhere you can drive to. Someone in Burnt Church, Tennessee is standing on gravel that is connected by touch to my street, just like someone is in Halifax, Nova Scotia. I can be in New York City in 3 days from my home in the suburban sprawl of Orange County, California without ever touching the earth.
