Minute Maid
Park (formerly Enron Field and Astros Field) is a ballpark
in Houston, Texas, that opened in 2000 to house the Houston
Astros.
The ballpark was Houston's first retractable-roofed
stadium, protecting fans and athletes from Houston's
notoriously humid weather as its predecessor, the Astrodome,
did, but allowing fans to also enjoy outdoor baseball;
something they couldn't do in the Astrodome. The ballpark
also features a grass field, compared to the Astrodome's
artificial AstroTurf, which was generally disliked by
professional baseball players. The largest entrance to the
park is inside what was once Houston's Union Station, and
the left-field side of the stadium features a train as
homage to the site's history. The train moves along a track
on top of the length of the exterior wall beyond left field
whenever an Astros player hits a home run, or when the
Astros win a game. The engine's tender, traditionally used
to carry coal, is filled with giant oranges in tribute to
Minute Maid's most famous product, orange juice.
