Tis the season for pumpkin carving and a new event celebrates the Halloween tradition in a big way. Pumpkin Nights, which opened Friday at the Minnesota State Fairgrounds, lined a mile-long trail with 3,000 hard-carved beauties. The path leads pumpkin peepers through 12 themed "worlds," from underwater enchantment to an outerspace-y "Pumpkin Galaxy." Pumpkin Nights is open through Halloween. All photos by Andy Witchger.
