Corn Crop Hindered By Wet Weather Ed McNamara has been farming in Goodhue County for 36 years. As the old saying goes, he's used to seeing corn knee-high by the Fourth of July. This year, he may not see it at all. "We've had wet periods but we’ve always been able to get a crop in. This is the first time that we've ever not been able to get the whole crop in," McNamara said.
