Right about wrong stanchion, and don't tell them 'hang on, let me look that up in my dictionary'... Some pilots even use the phrase 'mid-stanchion', meaning to say 'mid-span', I suppose.
Spots close to airports tend to be more critical ATC-wise than other areas.
Some routes show an intent, like the new North Shore Route over Long Island Sound--there's nothing wrong with flying higher than suggested or further off shore for instance.
Again, that's local knowledge, I'm not sure how they do it in D.C. or LA, or anywhere else they have HRCs, I've only flown here.
