My understanding about cross-country applications is that your chances are low, unless you have a connection to the area. For instance, if you are training in NYC, but have family in CA, you may have an in. Think about it as a program director/chairman in CA. You have a certain number of interview slots from which to come up with enough candidates to create a rank list that will reliably fill your class. With the numbers being equal (and there will always be someone that looks as good as you on paper), would you interview someone from NYC that has no ties to CA or someone who has trained somewhere in CA? The NYC candidate may just be shot-gunning, in hopes of matching somewhere good. No way to know for sure. That may not be a fair assessment, but.... For instance, I know of a guy who was 1st in his class, president of his class, ridiculous Step I score, and didn't get a single interview from a CA program. Ended up matching at a top 5 east coast program, though. There is definitely a coastal bias.
