If you are just passing through, or get stuck at the airport, or are awaiting a traveler to meet, this is a great way to spend some time! Its free, and its open when the airport is open! The main areas are by the luggage / baggage claim area, but there are parts of it throughout the airport that you will come across, at different gates, if you are a frequent traveler. My favorite parts are the vintage car and airplane, but its all fun! and free!
