Unless you're independently wealthy I'd scratch Alaska off your list. Hunting Alaska, even for residents, is generally very expensive and most grad students don't have a lot of spare cash. Of course you could road hunt around Anchorage or Fairbanks, but your chances of success are minimal. Your best bet is to focus entirely on what school can lead you to getting an ideal job so you can either live long term in a good state, or afford to go hunting in good states when you have a solid career.
