Nobody truly escapes reality via public transportation, not even on a long day's journey from Government Center to Aventura via Biscayne Boulevard (and on to Miami Beach if you want). Go surreal: Put the L'Avventura in your field trip to Aventura and turn this ride into a mind film. Friends afeared you've vanished to the point no one will ever find you, a cast of thousands, sights to behold or be filmed. Like Antonioni's dense tableaux, you may judge your encounter with mass transit as aggressively alienating and maddening in its slow pace, but by using your Truffaut-informed imagination (after steering clear of an aisle seat) and pretending you're chilling at Cinecitta instead, the vehicle transforms in that day-for-night way. As the Bluebird diesel rumbles north, downtown's hectic sets fall behind and the windows frame unbroken vistas of on-location neighborhoods -- housing, strip malls, construction sites, restaurants. Interestingly costumed extras appear, some more than once, making ominous eye contact or uninterpretable gestures. When you disembark at the mall, you will be astounded to discover that neither David Hemmings nor Monica Vitti is waiting to accompany you to the Gap. Ask the old woman in the heavy coat and sweater or the teenager appropriating black culture with his wardrobe but holding tight that platinum Visa just in case. Maybe Fellini should be your mental guide. At least until you enter the mall and walk head on into its 24-screen multiplex. A comedy turned tragic. So new wave.
