Hi DK,
Yes, I am a teacher I didn't work in the US because of my particular family situation (too many little ones). I did look at working though, and decided that it was really difficult for an expat. You have to basically sell yourself to the school districts and get your qualifications recognised, even though they are desperate for teachers. If you go on the unqualified scale (which includes all supply teachers), you get paid a real pittance - something like $40 per day.
I have to say that I had a real problem with the school system we were in - it really put me off education, and it took me a few years back in the UK to step foot in a classroom. I know there is such a thing as school refusing families, but I was a school refusing parent, LOL.
As for the area, I don't want to prejudice you too much. We moved from London area to Cincinnati and it was a real step down in terms of location. We were on an expat package which softened the blow. There are some really nice things, such as friendly people (as a Scot, you should be used to this), and kids playing on the streets on their bikes.
Springboro is very, very suburban, so you would likely be driving into Dayton or Northern Cincinnati to get to places of interest. Day to day, you will have lots of nice neighbours, and if you join a church, plenty of midweek activities.
