Concrats on getting a letter to the editor published in the March issue of the National Geographic. I saw it this morning at my Dentist's office. Your ideas seem sound to me.
Thank you. I've had other letters published in NG, The Economist, and elsewhere. Alas, except for American Express's Departures magazine, they don't pay. And NG won't fund my proposed expeditions.
But it's always nice to get one's ideas out there.
