The Dome was brought up in another area.
Then I thought about the Spruce Goose.
Countless movies, videos were shot there and is still very active. Hardly anyone knows what it is.
Could the Dome be turned into a Houston version of the Spruce Goose?
Houston is much more business friendly than Long Beach/So-Cal.
Your number is off by a couple of decimal places, according to the head of the Harris County Sports and Convention Corporation, which maintains NRG Park for the County:
Walsh said the county spends about $150,000 per year in utility and insurance costs for the Astrodome as a part of the larger NRG Park complex…
That’s 0.005% of Harris County’s $2.74 billion dollar annual budget. I think that counts as a drop in the bucket. (As an aside, Harris County has lowered its tax rate for five consecutive years now.)
