Kurt, you are trying to justify your situation by saying "I live in a big city. This is how things are here, so deal with it." It is you who should accept the nationally recognized terms and technicalities. You can have all the local lingo you want, but that does not change the fact that most other places might be different. This is not to say you should try and change your area's slang, but it is to say you should NOT try and say others outside your area should embrace an incorrect term. Also, if something is required in your area specifically I feel this should be noted. To say something is required, then to say "First, in Chicago, it's always required; we have different rules here. " is not very productive to anyone outside your area. One should be careful when stating codes that are notionally or universally recognized.
