This popular picnic spot is a great place for kids--even better than the zillionth viewing of Jungle Book 2. The plaza provides a sweeping view of airport operations, with takeoffs and landings close enough to smell the burning rubber. The big jets sometimes taxi and stop right in front of the plaza, where kids can wave at the pilots--and they usually wave back. A sound system at the back section of the plaza relays conversations between airplane crews and air traffic controllers. Pretty thrilling stuff for a kid. And free, too.
