I think it's a good point, and it's not just in the area that you mentioned. My daughter is working on her PhD in occupational therapy. In some areas the rules are different for some parts of the country. This is not unusual, I think, in some medical professions, but it is from time to time a problem and needs to be dealt with. We haven't run into it as a significant problem, but if it were to be a problem, I think we have the tools to allow us to deal with it.
