I live in a strange land of Dzhokhar-reminders.  Every workday afternoon as I exit the subway station on my way to work, I glance down the street to where Dzhokhar and Tamerlan stood at the marathon.  Then I walk past the memorial, to my office.  Every workday evening during the cab ride home from work, I pass by the infamous Shell station in Cambridge.  Having dinner at the S&S cafeteria, I'm in the heart of his neighborhood.   And I pass his high school as I walk to the drugstore.  Seeing these places so often, I gradually formed the idea for my story.
