This is either the biggest, ugliest corn rootworm you ever saw, or it's time once again for the Haunted Corn Maze at the Ron Domeier Farm. The Haunted Corn Maze will be open Friday, Oct. 12, from 7 to around 9 p.m. Cost is $5 per person. The proceeds from the Haunted Corn Maze will benefit the New Ulm Area Catholic Schools technology department. The Domeier farm is three miles west of New Ulm on County Rd. 27.
