I lived in Springfield for 3.5 years while I went to college, and I visit several times a year. Cost of living is very low--housing is lowest you'll find anywhere. City has everything you'll ever need but feels like a small town. Very excellent public schools. Excellent technical community college. Five other universities/colleges in town are all very good.
wages are low, but cost of living is low. quality of life is very good. springfield is on the edge of ozark mountains, and 30 minutes from Branson, MO and lots of fishing, camping, entertainment, etc. springfield is regional shopping headquarters.
excellent hospitals and healthcare.
Cashew Chicken was invented in Springfield. Old route 66 goes through springfield. Small zoo is neat. Ozark Empire Fair in August is fun. Hot and humid in the summer, not too much snow in winter (but they can get lots sometimes). Town is pretty flat/rolling hills. Lots of bible thumpers (said affectionately!) in the buckle of the bible belt.
I know chamber of commerce president and a few reps from convention and visitors bureau. e-mail me if you want contact info.
I would move back there in a heartbeat if I could.
Good luck.
