I grew up in Chicago. I love trains, public transportation, and maps. I listen to NPR and read a fair amount. I prefer a stick shift but my current ride is a bicycle. I live with my wife and our two cats in Mountain View. I spent the dot-com bust backpacking around the world, serving pizza, and making espresso. Last year I contributed some transit maps to a book about public transportation. I occasionally poste technical notes on my blog, under http://dannyman.toldme.com/category/technical/.
