great thread idea!
out of pure selfishness, i'll select this half-mile stretch of Lincoln Ave., from lawrence down to montrose, that constitutes the core retail corridor of my neighborhood, Lincoln Square.
google-drive south on Lincoln starting here:

the street already has a nice and cozy pedestrian plaza (created from a de-mapped section of side-street) that serves as the heart of the neighborhood, so expanding that out to make the whole street pedestrianized would be cool in my book.
giddings plaza:

too bad it'll never happen.
