I-75 + I-375 intersection, Detroit. Manipulated (in Preview, of all things).
Turns out I-375 is just over a mile long; that mile takes you downtown. (Yes, this is right in the city center.)
Paul Mison's random stuff that doesn't go elsewhere. Is it microblogging, or microactivity? (Previously known as 'tumblr is my sock drawer', for reasons that are somewhat unclear.)
