Walking from Concourse B to Concourse A at the Atlanta airport takes you through this walkway, which features leaf-like objects overhead, subdued lighting, and the sounds of a swamp. At least, I think it’s supposed to be a swamp, complete with croaking frogs, buzzing insects, and chirping birds. It’s a nice change of pace between bright, bustling concourses.
Just another reason to walk the big airports, rather than jamming onto generic underground trams with a hundred of your closest friends.
