I’m Theodore Roosevelt—though my friends just call me “Ted” (and no, I’m not related to the president, though I do share his love for adventure). I grew up in Detroit in the 1970s, back when the city was still the heart of the American auto industry. My first love was a rusted-out 1967 Mustang my father and I rebuilt in our garage when I was fifteen. That project taught me that cars have souls.
