Having done med school in Texas and in residency in FL, I know that the programs in both states have quite a few rotators, some more than others. It is a bit late to try an obtain rotations. I think your approach in the personal statement is fine, provided that someone reads the personal statement. I assume that most people read them all the way through, but with 600+ applications at major programs, it is understandable that some programs may not read it. Another option would be an email to the program director. In general, the people in those positions are receptive to emails from prospective applicants. There is a fine line there, but simply expressing your interest in a program or a given state may help. The bottom line is that the first consideration usually isn't where you came from, but when deciding between top applicants, distance from program can be a factor. The simple truth is that residents who apply to programs far from their current or previous locations are very unlikely to rank that program highly (with the exception of very well known programs like Campbell, HSS, Rush, etc...). Providing that information at the end of your personal statement would perhaps help in that situation, but the decision to put you in the possible interview pile will depend on things that have nothing to do with location.
