As an author of Empty Kingdom, I reside in San Francisco car-less. A lovely city with good public transportation, delicious food, and many other perks that makes this city great. Yet seeking solitude of the great outdoors that surrounds the Bay Area is difficult to get to without a ride. I’d find myself reading magazines and viewing photography of the natural wild. As a result, I’ve compiled images of the diverse terrains, lakes, mountains, and tropics that consists the beautiful color green.
