To commemorate the 150th anniversary of Gen. Wm. T. Sherman's tactical loss (but strategic success) against Confederate troops in the Battle of Kennesaw Mountain, visitors to the National Park this weekend can witness musket and cannon demonstrations, an outdoor presentation of a documentary film and musical performances. All will take place at Kennesaw Mountain National Battlefield Park, Thursday through Sunday, June 26-29. Information: www.nps.gov/kemo
