Welcome in advance, Merrie (hope I am not jumping the gun here, hehe)!
PA is such a large and varied state that I'm afraid you could easily become overwhelmed with responses from people.
There are homey, safe towns with proximity to colleges in all of PA's corners and in between, so to whittle it down, could you be able to give an indication of:
a) your budget for purchasing/renting a place to live
b) any preference in terms of climate (Northeastern PA is not for the faint of heart during the winter, whereas if you are a snow bunny, you may not want to move to Lancaster)
c) whether or not you have the need or desire to live near an urban center
I am sure people will be able to help you out,

and I wish you the best of luck no matter where you decide to relocate!
