The originating home of exploding scoreboards and bugle calls, Texas-sized dugouts (so that more fans could claim “dugout seats”), television monitors, Mercury-astronaut get-ups for the grounds’ crew, and every other imaginable Space Age gimmick—including air conditioning!—meant to modernize the National Pastime, the Dome sadly rusts away in the middle of a gigantic, empty parking lot while back-to-the-future retro stadiums flourish. (Even the occasional Funny Car exhibition, tractor pull, rodeo, or whatnot is barely a memory.)
Mickey Mantle hit the first home run at the Astrodome during a 1965 exhibition game. Undoubtedly before the first pitch was thrown, fielders knew the graceful steel web of support girders and glass, thro which passed the sunlight or reflecting artificial light at night, made it impossible to track balls hit in the air. Nonwhite baseballs were proposed. Ultimately, the roof was painted as daylight created the biggest problem. This killed the grass. (It was as if a greenhouse were painted black.) AstroTurf-8, an unforgiving plastic carpet requiring little maintenance and no water or light, was devised.
The modern sports era had begun.
Unless some new county-referendum vote is held with different results, here we have it: the Houston Astrodome (1965-ca. 2014). R.I.P.
