I had someone e-mail the other day asking for more information on a lighthouse image I photographed along the southern Washington State coast.
This wasn't your ordinary e-mail. The photographer was having problems finding exactly where I took the image. So he sent me a google map of the area showing in fine detail an overhead view of the lighthouse and surrounding areas. I was able to e-mail him back, giving him real time info on how far north he needed to go to connect to a back road to get to the trail head and the bluff where I took the photos.
