Hopefully I can be of some help. I went to Greenwood High School, so I'm rather fond of it. There are 4 high schools in Warren County. Three of them are "county" schools and links to their sites can be found here: high (broken link)
The "city" school is Bowling Green High School and their page is here:
Bowling Green High School
In my bias opinion I would prefer to go to Warren Central or Greenwood High School. If you want to have a better football team look toward Warren Central. You're not going to find a house with alot of Land (for sale) in the city school district in fact if any exist I don't know where they are. BGHS is probably alright if you want to look into it but I never liked it enough to want to go there. (good football team) Warren East High School is in my opinion where 90% of the country boy's go, I went to the middle school (WEMS) and there was alot of students that were going to go back to the farm life when they got past whatever school they thought they had to have. They didn't seem to care and the teachers seemed to have it rub off on them.
To go to GHS you would need to live out in Plano, Alvaton, or parts of Richpond and you can find houses out there that do have land although with the current direction things are going everything is turning into subdivision. WCHS you would look for a place out Browning, Rockfield, or parts of Richpond.
There is also a local college with 18,525 students enrolled, it's a nice university. In my opinion it's a well kept secret.
if there's anything else I can tell you let me know, i just threw this together off the top of my head so I'm not sure how helpful it is.
