Thousands of Bulloch County children were back in school Tuesday, but not yet for classes. With the start of the 2013-14 school year still two days away, parents and students throughout the district flocked to open house events, which allow teachers and administrators a chance to meet with parents and inform them on what to expect during the upcoming academic year. Open houses also give parents the chance to see the classrooms in which their children will spend the better part of the next nine months.
