Airports are places where various aircraft take off and land from. There are big, busy airports, like
O'Hare International, and there are small, quiet airports like where I am writing from,
Olympia Regional.
Many airports have flight schools where you can
learn to fly an airplane or a helicopter. Smaller airports have plenty of airport bums and ramp rats, which is a good thing since flying is fun to watch.
Sometimes airports will have museums, restaurants, and other fun activities.
