I was up at Leadville (LXV) a couple week ago and kept hearing calls that
were somewhat unintelligible, but the FBO staff & I were convinced
they were calling Craig and not Leadville. And we kept hearing these
calls. Still convinced they were calling Craig. Both airports have the same
UNICOM frequency and but are about 100 nm apart. About 15 min. later
a twin lands. They were calling "Lake County Airport". Now, that's the
"official" name but I've never heard anyone use it and neither did
anyone at the FBO! It's always "Leadville".

You can spot a flatlander 10nm vis away, I guess.
