But beware of what else could be in the farmer's field, say police. 'Tis the season for illegal marijuana grow operations, said Const. Kees Wijnands of Perth County OPP. Growers might have 15 to 20 plants in sporadic areas such as farmer's fields, swamp areas, wooded lots and along rivers, say police. The plants are still growing, with harvesting in late August and into September but police are warning residents to keep an eye out for strange activity. "If you see a vehicle parked on a back road, there is good chance someone is in the field fertilizing and watering their crop," said Wijnands. "They are not walking their dog," he said. Residents who see this suspicious activity should write down the licence plate and call police with the location of the car. Wijnands said corn fields are a popular place to grow marijuana because of the growth of the corn which obscures the plants. Wijnands said growers are often using GPS co-ordinates to locate their plants in fields rather than counting rows. Const. Ed Sanchuk of Norfolk County OPP in Simcoe said residents should also beware of booby traps such as overhead wiring or animal traps to stop others from getting at their crops. Also, sometimes growers put up "no trespassing" signs to discourage others from snooping around, he said. Police want observant citizens to call police. Don't touch the marijuana or dispose of the plants yourself, he said. Olaf Heinzel, spokesperson for Waterloo Regional Police, said local drug officers will scour nearby fields in the region in September during harvesting season. But residents who see others out at night or cars on the side of the road or abandoned bags of fertilizer or trays should call police. The local drug tip line is 519-650-8500, ext. 8446. For the OPP, call 1-888-310-1122 or Crime Stoppers at 1-800-2228477. - --- MAP posted-by: Jay Bergstrom
