Joanne--what a neat idea, to have a husband "fine tuned" :-) But seriously, that sounds great, and we'll be interested to learn how it works out. Even though Peter is not eliglble for things like that,or pallidotomy, it's good to know that there are procedures which can really help some of our "tribe" manage this yucky PD better! Good luck with the backpacking--- Camilla Flintermann, CG for Peter,76/6+
