A type of stadium
where the roof
can be moved into place when necessary, then pulled back when not necessary. This allows the benefits of an open-air stadium, like a natural grass
field and sunlight
, but keeps out annoying things like rain
and stifling heat
when such things would interfere with the game
being played, or fans
' enjoyment thereof.
The first such stadium was SkyDome in Toronto. The ranks now include Bank One Ballpark in Phoenix, Safeco Field in Seattle, and Enron Field in Houston.
