Selection of away rotation sites

in search of some advice, especially from someone who's experienced a similar situation...

i'd like to head to the west coast for residency, which might be difficult as an east coast med student with midwest roots. i'm planning to do two away rotations, with at least one on the west coast. i'm having trouble deciding where to do my second away rotation. a second away rotation on the west coast might increase my chances of landing a residency spot in the pacific time zone, but i'm afraid that it could also turn off east coast programs as i might seem disinterested in staying on the east coast. while landing a spot out west would be ideal, i also would like to keep the broadest number of options available.

thoughts? thanks.
