A referendum to turn the Astrodome into a convention and event center was shot down.
Right now, it's in a sad state...it hasn't hosted a sporting event since 1999, and has been shuttered since 2009 (though the press has signed waivers to get in to show how dilapidated the interior has become in recent years). Seats are torn and dusty, the field is a mess...vandals have broken in and smashed glass...pipes have broken. It's definitely in pretty bad shape.
Sure, it seems dated now, but it was called the "Eighth wonder of the world" for a reason back in 1965. It was cutting edge for its time, being the first air-conditioned, completely domed stadium. The four-story scoreboard and the lighting animations were very cool to look at right up until they were removed in 1988 (sadly, they were jettisoned for 15,000 more seats, which locals said definitely took away some of the charm of the 'Dome). This building really meant a lot to the people of Houston, and many are sorry to see it go.
Check out the animations that would play on the big screen....keep in mind this was 1965:
And here's the other animations...this was impressive technology for the era...absolutely mindblowing for spectators:
I never got it to see a game there in its heyday, but I really wish I had. Really was a marvel.
