WHERE'S MAXWELL SMART?

There just might be a spy in your pocket.

The Defense Department has discovered a new espionage threat for American contractors who travel back and forth to Canada.

It seems tiny radios frequency transmitters have been found inside Canadian coins to track the comings and goings of defense contractors.

No one knows (or they aren't revealing) who or why Americans are being tracked, or how these contractors were given the coins in the first place.

Sounds like something out of a James Bond movie.

The next thing you know, someone will invent transmitter-laden underwear to track spouses who might be cheating.

In that case, it would be advantageous to incorporate an invisible-fence feature so if they push the limits ... like the dog that they are ... you could shock 'em back to their own backyard.

Then again, who'd want them back?
