KENNESAW

Civil War artillery demonstration

Don’t be perturbed if you hear booming coming from the direction of Kennesaw Mountain National Battlefield Park this weekend. It’s just the rangers and living history volunteers reminding everyone what a real cannon sounded like. Five times on Saturday and again on Sunday they’ll load the Civil War-era, 3-inch ordnance guns and set them off with blanks. In between shots, experts will explain how the guns were operated, loaded and transported to the battlefields. Visitors are also welcome to explore more Civil War armament in the visitors center.

10 a.m., 11 a.m., noon, 2 p.m. and 3 p.m. June 27 and 28. Free admission and parking. 900 Kennesaw Mountain Drive, Kennesaw. 770-427-4686, nps.gov/kemo.

WOODSTOCK

Adult Skate Night

Still nostalgic for the roller rink of your youth — that cool Friday night hangout where you’d go to listen to new music and maybe grab your crush’s hand for a few rounds? The Hot Wheels Skate Center is ready to bring it all back. Grab your old skates from the back of the closet or rent a pair once you get there ($4 per rental) and hit the wooden floor. DJ Silver ATL will play a variety of skate songs, from disco to dance, Whitney to Britney. Adults only, though, so anyone younger than 18 won’t be admitted.

6-10 p.m. June 28. $8 ($4 skate rental). Hot Wheels Skate Center, 228 Farm Ridge Road, Woodstock. 770-592-4688, hotwheelsskatecenter.com.
