Stock, not sure if this a good or bad idea, but it might be in your best interest to bring a tape recorder. This way their is no misunderstanding about interpretation of conversation. Its laid out exactly as stated (and nothing is overlooked). They may shy away from this and not be as forthright with their answers as a result, so use your best judgement (if you hadn't already considered this).
thanks to both you and airys for taking the time to do this. it is certainly appreciated by all. Good luck.
