So to maybe make Lon feel a little better about
his strange habit, I must admit that I have been tracking RJ locations on Google Earth.* I've looked up Gia's place on Sutton Place, I've tracked Jack to Bermuda and Nantucket (I think I located almost exactly where the safehouse is) and Red Hook (I also think I found the warehouse, aka HOME). I followed him to John Jay park near New York Hospital and even found the pedestrian walkway over the FDR.
The attention to detail that Paul has in the books is seemingly near perfect. I only say 'near' perfect because I couldn't figure out how the safehouse is "directly north" of the Wauwinet Inn.
*I know, webby, I know, but Google Earth is just too freakin' cool. :p
