leonI was born in 1961 and remember the Astrodome getting built.....they don't get anymore round than that. It was far thinking at the time. It's still in existence today but not being used......Here's an excerpt taken from Wikipedia...
When the Astrodome opened, it used a natural Bermuda grass playing surface. The dome's ceiling contained numerous semitransparent plastic panes made of Lucite. Players quickly complained that glare coming off of the panes made it impossible for them to track fly balls, so all of the panes were painted over, which solved the glare problem but caused the grass to die from lack of sunlight. For most of the 1965 season, the Astros played on green-painted dirt and dead grass. As the 1966 season approached, there was the possibility of the team playing on an all dirt infield.
The solution was to install a new type of artificial grass on the field, ChemGrass, which became known as AstroTurf. Because the supply of AstroTurf was still low, only a limited amount was available for the home opener on April 18, 1966. There wasn't enough for the entire outfield, but there was enough to cover the traditional grass portion of the infield. The outfield remained painted dirt until after the All-Star Break. The team was sent on an extended road trip before the break, and on July 19, 1966, the installation of the outfield portion of AstroTurf was completed and ready for play. The infield dirt remained in the traditional design, with a large dirt arc, similar to natural grass fields. The "sliding pit" configuration, with dirt only around the bases, did not arrive in Houston until the mid 1970s.
