just to throw another wrench in this dilemma-- i have solid numbers and a solid application (i think), but no ties to Colorado (did not rotate, noone from my school is there, i go to medical school on the other side of the map, etc.). Basically i clicked a button on eras and I got an interview. on the flipside i rotated at Harvard, had an amazing rotation, received an honors, was told by the course director and numerous residents that they were looking forward to seeing me at interviews, and was sat down by one of the chief residents before I left and told "you are going to be able to match at your number one program, if it's harvard you have to let me know and i will go to bat for you." In the end they did not give me an interview.
My advice going into away rotation scheduling then is: if you are going to do an away rotation at a program that you have no ties to and has a history of not giving interviews to some rotators, then schedule another rotation at another great program (or two) that do have a history of matching/interviewing rotators. Wherever you go, work your butt off, be reliable and outwork but don't outshine the residents, be fun/friendly to be around, and hope for the best. also, make sure you ask for a letter of recommendation so at least you come out with something.
