John Baichtal interviewed me recently about The Geek Atlas : John Baichtal: What is the most notable omission from the first book? John Graham-Cumming: Hard to say because there's not one glaring omission that people bring up consistently. Everyone's got a favorite place and some aren't in the book. Lots of people wanted more NASA locations, but that would probably fill an entire Geek Atlas! Lots of people wanted more sites in Asia. If there's a second book I'd include some optical telescopes because for some reason (a mystery even to the author) there are none in the first book. You can read the full interview here .
