Authorities have found an out-of-the way plot of marijuana plants near the town of Peterson in northwest Iowa, but the plot’s cultivator hasn’t been found yet. Clay County Sheriff Randy Krukow says they’ve seized four-thousand marijuana plants from the plot Experts say each plant will produce about a pound of pot. That 4,000 pounds would translate into about four million dollars on the street, according to the sheriff. The discovery is part of a sweep that involved a National Guard helicopter. A deputy in the helicopter discovered the plot among some trees in a small clearing. The deputy took some pictures, and a judge granted a search warrant. The sheriff says they haven’t determined who was cultivating the plot because it was in such a remote location. “This is back in the timber and it’s a remote area that unless you had a right to be there, you would not find it,” he says. Sheriff Krukow believes this bust will put at least a temporary dent in the drug trade in the Spencer area.
