When I lived in Colorado, it was all 303. You only needed seven digits to call around the neighborhood, and just a 1 and the number to call from Denver to Colo Springs, for example.
But now I'm seeing that 303 and 720 co-exist in the same towns. Do you have to dial 10-digits to call ANY number now? Even if it's the same area code and right next door?
And what about the 970 area code? You have to dial a 1+ the 10 digits to call that from Denver, right?
