Bone_Jock, although you certainly have excellent insight into the process of applying to Mayo, your statement that Mayo does not call its applicants is false.
Last year January I received a call from Hannsen at home, and he asked me if I had any questions and told me that he felt Mayo would be a great place for me, etc. I knew I wasn't ranking Mayo 1st so I was polite and appreciative, but noncommittal. I ended up matching at a program I had ranked higher than Mayo, so I don't know what would have happened had I dropped to them, obviously.
The bottom line is this: don't believe anything anyone tells you until after match day...because none of it is binding until then.
Good luck to everyone this year!
