John, It sounds like you and Nora will be on the road soon. Good "Luck" probably isn't the best we can offer, let's make it Good Medicine and the Best Doctors instead. Luck is for lotteries and card games, you need the best care anywhere and Mayo is just the ticket. You've got a lot of people pulling for you around here, keep us current, travel safely, and come back stronger than ever. All the best!
