Thanks for the replies gimlet and seamonkey. I think I'm like everyone else ranking right now, as the deadline approaches you start doubting and second-guessing.
All of my family is in TX. They have all encouraged me to do what I want, stay in state or leave, and not to worry about the distance. I don't go visit more frequently than Q2-3 months, but I think it's knowing they'd be so far that freaks me out a little. I'd also like a place where there's a good chance of meeting someone, not to sound like I'm hunting for manflesh, but don't necessarily want to meet him in a seedy bar.
Boston seems cool but it's expensive, heavily taxed, and really the only thing drawing me there is the Harvard name.
SA seems solid to me, Dr. Andrews I really liked, but there are some things that bother me, namely the city (I was born there but don't really like it all that much), and lacks some amount of prestige.
UTSW seemed alright, no real complaints other than Parkland is a beast and that lingering malignant reputation, although the residents I spoke with refuted it.
Vanderbilt seemed good, great salary, benefits and name recognition, but I also heard the men sometimes call themselves "Vandy dandies".....wtf????? Eww. And although technology is great, it kind of seems over-wired...like, what would happen if the electicity went out or nuclear war? Maybe I'd become over-reliant. I dunno.
UAB I had no complaints, seems to have everything, including rep, with the exception of location like everyone repeats ad nauseum. It was my first interview and I kind of held other programs against it as the season went on.
So as you can see, all of these places have pros and cons (imagined or real), and exactly like you said, I'm afraid of regretting my decision to rank a given program #1 vs #4 and all that. What I really want is some experience in the world, and part of me knows it's good for me to get out of TX and live in a different state. Then another part of me says what if I have a s****y week and just need to see my sister or brother, and what if my parents need me if they get sick, etc. Moving somewhere out of state is one thing, but being committed for 3 or 4 years is almost overwhelming.
I appreciate seeing how other people view the programs and what their impressions are, and even if it ultimately doesn't influence my list, it at least helps with the nerves.
