JMHO
barkley.. we are originally from Illinois.. left 25 years ago.. Marine Corps, then Civilian life kept us in California. We spent the last 12 years up in the Bay area.. San Jose.. then moved to Rural Hollister... loved it all except the cost of living was getting insane.. But the salary scale in CA.. is higher than the Midwest.. We returned this when Dh's company had an opening at a Midwest plant. It was a wild ride.. try a search on my name around June..
That being said we live in the MetroEast of St. Louis.. that is the Illinois side of the Mississippi River. I love that the cost of a house is HALF the price of the Bay area. Car and home insurance is about 2/3 what we paid in CA. People are very friendly, we live in a racially diverse area that is close to Scott Air Force Base. I am VERY pleased with the school system, altho Illinois itself is not highly ranked, our school district is very good.
There seems to be a HUGE number of Churches and Lawyers here.. Banks and Taverns (not Clubs) are also numerous. It is Autumn now.. and it is GORGEOUS! Food is served in huge quantities and it costs much less to go out for a great dinner. We are 20 minutes from St. Louis so we are close to theathers, river casinos, metro night life, professional sports, festivals and art galleries. and Girl.. these people do not know BAD commute traffic! LOL.. sure it slows down during commute.. but there is no extra hour added to your commute due to traffic jams. There are many rivers and lakes which to enjoy. Money just seems to go a little farther here.
Now.. for the flip side.. No Pacific Ocean..... the roads are horrid.. great googlie mooglies! There is construction everywhere that doesn't seem to improve the rough, ragged,bumpy roads. Finding an avocado, fresh lettuce, and California style produce is more than difficult. LOTS of CHEESE, MEAT and BACON! STARBUCKS.. few and far btwn.

I live in one of the nation's Highest areas for litigation (ah the vast amt of Lawyers...) It is hot, hot and HUMID in the summer and COLD in the winter.. and My HIGH utility bills prove it. Real Estate taxes in this county are higher than CA. It is somewhat conservitive.. but not too uptight. We have run into some bold, negative racial attitudes .. and we don't go looking for them

. People smoke more here.. and there is smoking in restaurants!

I was spoiled in CA...
The work ethic here is strong. In general people are very kind and generous to others.
am I happy here... yes. Would I ever move back to CA. if I could afford a house? Yes, if I could get the rest of our family and friends to move out west too.
It was hard to take the Midwest Farm outta the girl when we left 25 years ago.. it is now hard to remove the California girl... but you know what...
I think I have been darn fortunate to experience so many different people in my life. It makes my life more interesting that is for sure.
Best wishes on your next adventure!
