Jeff provided and Mike loaded software into the blog which allows you to know where my phone is any time of day.  It is google software which uses the GPS in the phone to plot its location on a map.  The "Trip Locator" button on the menu above will take you to the map.  Unless you care which home improvement superstore we are shopping at or which kid we are visiting, it won't be of much use for a while until we start travelling again.  When the phone can't see the necessary GPS satellites, it will triangulate an approximate location from cell phone towers.
