My dad lived somewhere near where the Colt 45's originally played. If I remember correctly, he said they practically threw Colt Stadium together overnight.In 1962 my uncle drove me to Houston from Amarillo to see the Colt 45's play the Reds and Pirates. It was pre-Astro Dome, played in an outdoor stadium. We were really excited to see major league baseball in Texas. Someone pointed out to us that Kansas City was closer to Amarillo if we wanted to see Major League Baseball. But it just wasn't Texas.
Once the Astrodome was completed, they tested what would become astroturf in the old stadium. Supposedly allowing people to ride horses & drive cars over it to test its durability.
Supposedly, the Colt Stadium was dismantled, sold and shipped down to Mexico. No idea if it is still being used somewhere today.
