I recommend sending off for some information from the local schools. There are Lexington City Schools, Buena Vista City Schools and Rockbridge County Schools. Some students are home schooled or attend private schools such as Stuart Hall which provides bus service to Lexington.
The folks at Rockbridge Area Tourism are happy to spend time talking with people both in person and over the phone to help answer questions. The Lexington/Rockbridge Chamber of Commerce can provide all sorts of concise profile sheets of and brochures on the area.
There is also a Newcomers Club and a Mom's Club, and I'm sure that they would be happy to answer any questions that you might have as well.
Please use this website created by the volunteer organization "Rockbridge Area Information Line" for contact information for all of the groups that I mentioned above:
