Thanks for comments. I don't know how far our Phd idea will go. Not far, I hope but these things have to run their course. Our faculty is great at procrastination so it will take us a long time. I'll be in DC January 10-12, staying with Diane DeGrazia, I think. I sure hope we can get together. Am trying to get David to come down for the weekend but he can't tell yet what his obligations will be. Susan
