I've personally seen $225-250K starting salaries for "partnership" track in both SoCal as well as FL, so I would expect a PP in Peoria to pay a little more, even in a partnership track situation. But again, I am going off numbers from several years ago when I first started the job hut. No one can say for sure what is going on with the job market now (certainly neither of us, considering I am attending several years out, and you're still a resident?), but the fact that a rural position in IL and a rural position in GA both posted starting salaries around $250K does give me pause.....
(and yes, $250K starting salary strikes me as low for a rural position away from the coasts, either partnership track or employed, at least when I was looking several years ago)
