St. Louis' renowned ghost hunters, the Monster Paranormal Crew, were invited to conduct a paranormal investigation of the Victorian section of the Missouri Botanical Garden (4344 Shaw Boulevard; 314-577-5100 or www.mobot.org). The startling results of their mission are revealed tonight from 6 to 9 p.m. at the Spirits in the Garden celebration. Attendees can also participate in the Wicked Plants Scavenger Hunt and show off their Halloween spirit in a ghastly costume contest. Halloween-themed cocktails from Wood Hat, Pinckney Bend and other local distilleries haunt the grounds, and DJ Rob Levy monster-mashes it up, spinning spooky sounds. Admission is $35 and includes a commemorative tasting glass, samples from the distilleries and plenty of appetizers. Designated drivers pay only $15.
