Sunshine Treat

From Tardis Wiki, the free Doctor Who reference

The Sunshine Treat was an activity on 30th century Earth. The Sunshine Treat was practised by citizens that lived in the underground cities. They took a lift to the surface, and, once up there, were able to walk, see the earth and the Sun, experience sunlight directly. It was described as expensive by a colonist.
