Can't speak for Miller (didn't go there!), but your pros for FSM are spot on (although I don't know personally about the MSTP admin). While I went to UG on the east coast, I grew up in SoCal, so yeah Winters were different than that, but get advice from a local about a good jacket and you'd be fine. I was definately not in the top half (or even the top 3/4) of their admit profile, so had a little imposter syndrome, but was assured that they wouldn't let anybody in who didn't have the potential to thrive - and they were right! Also wasn't ophtho, but knew a couple and they both matched to their #1.
