Grew up in Newton, about ten miles from where she was found. Was born in '89 so this was after my time, but there is definitely nothing in that town but farm land.
Hwy. 91 is a common route for truckers heading up from Florida to other east coast destinations, she must have either snuck onto a truck and jumped/fell off, or hitch-hiked and was pushed out.
Sleuthed the states with red from Isomap linked above (NY, VT, NH, ME, MA, NY, PA, WV, NM, AZ, NV, CA, OR, WA).
Below are five missing women that could not be ruled out* as not being Jane Doe: (In no particular order)

Does anybody think that we can rule out any of these five women?
* Many other women fit the profile of Jane Doe, but had DNA samples on Namus that had "tests completed", so the assumption was that this these women are automatically ruled out
