You are so lucky to be going to Mayo!! And you sound very focused and very much in control. At least you will have gone to the top guys in the country. I hope that this trip will be one of the most valuable and informative experiences you can have...one that will give you more answers than you currently have. And it’s great to have someone with you who can listen and ask questions that you might not think of. Of course we’ll all be waiting to hear everything. Once again, best of luck. You'll be in my thoughts.
