The area around the new Carnival Center for the Performing Arts isn't exactly swanky. For the four-wheeled flocks that descend come showtime, the thought of parking on the street is a piss-in-your-pants proposition. Most would rather pay $10 or $20 to leave their automobile in a lot, or more for a valet. You, however, are a sensible city dweller with your wits and little cash about you. So head west on NE Thirteenth Street from Biscayne Boulevard and turn right on NE First Court. Most nights, especially if you arrive fifteen minutes or more early, you'll find a spot on this somewhat hidden two-block stretch. Nothingç Try Thirteenth Terrace perpendicular to NE First Court. Feed the meter and walk the block or two to your show. No pee needed.
