Hi all, I have prepared some new maps from the 25 positions listed on Dan Allen's web page http://www.nwlink.com/~danallen/center.htm and they can be viewed at: http://www.phys.uu.nl/~vgent/images/sphere1.gif http://www.phys.uu.nl/~vgent/images/sphere2.gif The 'centre of gravity' (blue spot) refuses to leave the Hudson Bay area. The contour lines drawn on both maps indicate the AVERAGE distance (in units of 1000 nautical miles) that each of us (denoted by the red spots) has to travel to get to a particular meeting place. As in my first efforts, the optimum location (as far as travel distance is concerned is still in the Great Lakes region. The minimum (average) travel distance is about 2880 nautical miles to a spot near 91.5 degrees West and 54 degrees North. The maximum (average) travel distance is about 7920 nautical miles to a spot near 91.5 degrees East and 36 degrees South. The maps also nicely show that, with two or three exceptions, everyone listed on Dan's web page lives close to the sea (I guess that this will hardly surprise anyone).
