We've heard all sorts of stories about how the bad guys try to get illegal drugs across the Mexican/American border.

They put dope in tires, in watermelons, buried under (or in) sacks of food, in the lining of clothes...and on and on and on.

Heck, they even insert dope inside their own bodies. Ahh...let's not get into that.

But here's a new one. How about making a cannon and just firing the the pot right over the fence? Heck, no mess, no fuss that way!

AP) - Police in the border city of Mexicali say they have recovered a powerful improvised cannon used to hurl packets of marijuana across a border fence into California.

Police told the Televisa network that the device was made up of a plastic pipe and a crude metal tank that used compressed air from the engine of an old car.

The apparatus fired cylinders packed with drugs that weighed as much as 30 pounds, police. It was confiscated last week after U.S. officers told Mexican police that they had been confiscating a large number of drug packages that appeared to have been fired over the border. Mexican police on the border have recovered a series of similar devices in recent years.
