HBO's sports program hosted by Bob Costas reported that Durham Connecticut is equidistant and therefore the geographic center on the road between Foxboro Stadium, home of the New England Patriots and Giant's Stadium, home of the New York Giants. So, of course, I didn't believe them and went to some of my resources.
To start, the distance between the two stadiums as calculated for the quickest route is exactly the same at 209 miles using either Microsoft MapPoint or Google Maps. Just for reference, the straightline, "as the crow flies," distance is about 190 miles.
If you add Durham to route calculations for both methods of calculating the fastest route, the distance comes to 225 miles for both MapPoint and Google Maps...that's a good thing, of course if you believe the HBO progam. But clearly, the HBO program wasn't using a route calculation. If you use the quickest route, my calculations puts the center around Westbrook, CT along Route I95.
What do come up with?
The shortest TIME route hugs the CT coast on 95 through providence and is 208 miles going from MA to NJ. But the shortest DISTANCE option in the same direction is 198 miles avoiding the coast and passing close to Durham. The exact Center point of the route is at St. Sebastian Cemetery lat/lon 41.546649, -72.703271.
The distance between the crof flies center point and the shortest drive center point is 6.99 miles.
Here's a link to the map i did my calculating on

The funny thing, was that it's for sale, and we were actually looking at it before all this discussion occured. Haha, quite the coincidence.
