Except for the scenes set in Cairo, I’ve personally scouted the geographic locations for all chapters in the book and determined the GPS coordinates using a Magellan Meridian Platinum handheld receiver. Below are Google Earth satellite pictures for most of those sites. For those chapters where you see no images below (e.g., all locations in Johnstown, Pennsylvania), the Google Earth images were too course to be useful. You might try them again in case the imagery has been updated.
Note: to get a larger, blown-up version of each image below, click on the image.
