This was the origins of what we now know as the Astrodome. I assume this photograph was taken just over 50 years ago, when ground on the domed stadium was broken on January 3, 1962.

Before you roll your eyes and assume that the gentlemen firing hand guns into the earth are nothing but country rick bags, it’s worth noting that the idea for building the very first multi-purpose domed sports stadium came to Mr. Roy Hofheinz while he was on a tour of Rome. There he learned that the builders of the ancient Colosseum installed giant velaria to shield spectators from the Roman sun. After all, watching gladiators murder each other would be uncivilized without a properly constructed awning.
