“This is a very quiet county, a rural county and growing fields of marijuana is not part of what’s going on here,” Pine County Sheriff Robin Cole said. “I live five miles from it, and I was very surprised. The plants were about chest high, so we got in there, and got them at the right time.”

The raid started early Wednesday morning, and Cole said authorities don’t know who planted it, how it got there, or where it was going.

Officials loaded the marijuana into a dump truck where it’ll be taken across the state to a facility to be burned, stopping it from entering the drug market.
