OK, yeah, we admit it. Sometimes we time it. We synchronize our exit from I-595 eastbound to I-95 southbound, or switch from I-95 northbound to I-595 westbound to coincide with the landing of -- whoooooooooooooooooooosh -- a jumbo jet. What makes this experience, well, such fun is the same thing behind the appeal of roller coasters: all the fear, none of the consequences. What if the pilot gauges it wrong? Luckily it's never happened. And you can get even closer to the planes by driving around Perimeter Road, which is open to the public and hugs the airport fence all the way around. Still, we prefer the spontaneity of a chance encounter, as well as the terror demonstrated by some motorists who are obviously not in the know. In very few places on Earth do three major traffic arteries -- I-95, I-595, and Federal Highway -- nestle so close to an airport. Enjoy it.
