Yeah, the Atlanta Braves are outside the city of Atlanta now. It's not unusual.
Speaking of airports, back when I was flying, the Cincinnati airport had grown into a Delta hub and was pretty large so it was reclassiied from Class C to Class B which significantly enlarged it's air footprint, the region where you could not enter without a clearance. Most of us just flew around it, I once tried to get a clearance and was denied. So, now it's MUCH smaller and less busy but still Class B.
I have heard of visitors thinking they were lost when a pilot tells them "Welcome to Kentucky." on landing.
(FYI, Class A airspace is just the region between 18,000 and 60,000 feet, not related to any airport. You can't fly in it legally without being instrument rated. There is a story about an SR71 requesting clearance to enter at 60,000 feet (FL60) and the clearance was granted if the plane though it could get that high and the SR71 said "We're descending.")
