Visiting the population centre of US

From the BBC's Matthew Davis:

Here in Edgar Springs the United States does not feel like a country of 300 million people. This is a blink-and-you'll-miss it kind of town - with a population of 190, little more than a petrol station and a few dozen houses at an isolated crossroads on the edge of the Mark Twain National Forest. Six years ago, Edgar Springs experienced a brief moment of acclaim, when the US Census Bureau proclaimed it the new "population centre" of the US. That is the notional point at which a flat-surface representation of the US would balance if everyone counted in the 2000 census stood up in their homes.
The distinction - calculated every 10 years as an aid to understanding population distribution - is marked by a small plaque outside the town's cemetery. But really this swathe of the Mid-Western Bible Belt is more like the hole at the centre of a "population bagel."
