The first two years of NASCAR’s Chicago Street Race were accented by rain, but maybe the third edition will be a charm for fans and drivers.

One full weekend of cooperative weather would be nice. You could even call it a parting gift if you like. That's right, this is looking like it'll be the final Chicago Street Race — the third installment of NASCAR's original three-year contract with the city.

The streets of Chicago are home to the only NASCAR race these days that doesn't take place on a dedicated track. This is what it takes to make sure the event runs smoothly and safely.
