Bumper to bumper to bumper on I-95. Multicar pileup? Construction? Who cares? You're stuck. But the left lane promises release. You careen up and onto the turnpike. The on-ramp curves up and around and so do you, swerving madly to avoid the little blue Toyota doing 20 and the silver Lexus doing 90, both of which want your spot. Having successfully defended your turf, you cruise on up to the toll plaza at the Golden Glades Interchange. You shoot through the SunPass lane, and in no time you're making speed, a blissful smile on your face. But you've done more than escape gridlock. You've penetrated the barrier between two worlds -- from lunacy to normalcy, from citified to sedate. You've crossed the county line. Miami awaits your return.
