Interesting.

What is the easiest/simplest way for a person to find their GPS coordinates and copy it for insertion into a text message if using an Android phone?

By easy/simple I'm thinking with the least learning and highest likelihood of success when tired or slightly paniced.

Also, what format do you feel is easiet for potential rescuers (both neighbors and professionals) to use?

How might a typical neighbor use the coordinates to find the boy?
