Nickname for San Antonio.

Why? The area code is 210 which is a number countdown. Two... One... Zero

Countdown City is neither Orlando, or San Antonio. Orlando's area code (Orange County) is 407 and San Antonio has no historical relevance to be called "Countdown City"...

Area code 321 is the area code serving Brevard County, Florida. The area code has been in use since November 1, 1999; it was assigned to Florida (instead of suburban Chicago) after a successful petition led by local resident Robert Osband to commemorate the Space Coast's impact (NASA/Kennedy Space Center) on Brevard County, thus coining the term "Countdown City". Although the real Countdown "City" is technically Cape Canaveral, the entire county claims the term as it's own.
You will find a lot of rocket scientists living in Countdown City.
