Nygfan84, I agree with you there. While it's fine to use the identifiers for the well-known airports, it's silly to refer to the local airports by only their identifiers - only you and the people who live nearby probably know it, or care to know it. I don't think it would hurt to use both the name and identifier for clarification purposes in these cases.
Sure, we can always refer to some website to find out, but it wouldn't hurt for the people who post to clarify that and save us that trouble
I can talk about EWR and most people will know where that is. But if I start saying 47N, LDJ, TTN, CDW, then I'd be sending most of you to some website to find out what on earth I'm talking about. Like someone said earlier, it seems that people like to pretend they're smart because they know the codes
