Jack-o'-lantern carving at the Denver Botanic Gardens.

DENVER, CO - OCT 13: Artist Greg Butauski from Columbus, Ohio, has carved 3-D sharks on to one of the large pumpkins. It takes Greg about two hours to carve each 3-D creation. Jess Parrish and his artists from Cool Hand Ice Carving from Longmont are hard at work at the Denver Botanic Gardens using their ice-carving skills to carve 266 jack-o'-lanterns for the first Glow at the Gardens event on Wednesday night, Oct. 14, 2015. The expertly-carved pumpkins will be on display through out the gardens including traditional and those in large stack displays, as well as 33 sea-themed jack-o'-lanterns. There are two more Glow at the Gardens events on Wednesday nights, Oct. 21 and Oct. 28, 2015. (Photo by Kathryn Scott Osler/The Denver Post via Getty Images)
