Much like ill-mannered in-laws, ghosts often show up uninvited, walk through your newly spackled walls, and scream uncontrollably when you say their name three times into a mirror. Experience safer family fun with today's Groupon: for $15, you get two tickets to the two-hour Roswell Ghost Tour in Roswell (a $30 value for adults, or a $20 value for children 12 and under).

Interweaving Georgia's Civil War past and paranormal present, the Roswell Ghost Tour channels the charm of the Deep South and the ambling spirits of the undead into a one-mile tour through Roswell's haunted history. Tour operator and head guide Dianna Avena wrote Roswell: History, Haunts and Legends and, along with her husband, has been spotted dishin' on apparitions in a number of radio and television shows, most notably an episode of SyFy's Ghost Hunters. These active spectral spies helm a legion of learned guides who will lead the wannabe-spooked through a two-hour tour focused on real-life frights. Along the way, scope out the paranormals who still reside in gorgeous Antebellum and Grand Greek mansions such as Bulloch Hall (home of Roswell's founding family), the former mill at The Bricks, the Civil War burial ground at Founders Cemetery, and the Confederacy’s favorite Dairy Queen. Since Roswell's passionate phantom phollowers believe that the spooky tales shriek for themselves, they pride themselves on leading a tour devoid of phony accents, costumes, scary flashlight faces, blood-curdlingly bad Crypt Keeper puns, and other ghastly gimmickry.

The Roswell Ghost Tour recommends bringing flashlights, umbrellas, comfy walking shoes, proton packs, and insect repellent. The event is not recommended for restless small children, who may get tired from all the walking or are already jaded by crummy Casper sequels.
