Remember that story that came out last year, the one about the American contractors claiming that Canadian spys had implanted a secret device that could track their movement and locations? Well, here is a picture of what they THOUGHT was a secret device:

It's true. Read
this story on CNN.
I am not a spy, but i think that after years of watching "Get Smart", various James Bond movies (not the Roger Moore ones), reading "Jacob Two-two and the Hooded Fang" and watching 2 episodes of "24", i believe that i am more qualified than the American spy experts.
First, if i were a spy, i would actually not think it was a good idea to implant a secret nanotech radio device into a quarter. Why? Because people spend quarters all the time. I think that a quarter on my person has a life time expectancy of about 10 minutes - before i make a phone call or buy a coffee or donut.
I think that if i wanted to plant a tracking device onto an American Contractor, it would probably look more like a Spidey Tracer. I understand that there is some logic to making a spy bug look like an everyday object, but coinage is a little too everyday to be practical. It would sort of be like making "nano-kleenex"...
Second, if i WERE dopey enough to put a tracking device into something like a quarter, i wouldn't disguise it by painting it BRIGHT RED and putting it DEAD CENTRE into a coin. They printed (minted?) up millions of these commemorative poppy quarters. A quarter that actually used tracking nanatechnology would be very expensive to make. We're not a rich country. We aren't fake-rich-on-credit like the States. We cannot afford to get involved in costly wars, or invent all sorts of crazy weapons and gadgets in order to spy on people. We can't even afford to keep real maple syrup in most of our pancake restaurants!! And, do we actually even have REAL nanotechnology yet - and i'm not talking that crap that Scientific American reading geeks call nanotechnology - i mean actual real tiny robots like in sci-fi novels that can regrow limbs for you and stuff? Does real nanotechnology - and i mean the good fancy kind - actually even exist? (And if you're going to write in after popping onto Google, yeah, i read the first thing that popped up too (wikipedia, anyone) so don't bother!)
Third, why would we spy on the Americans? Why? We know EXACTLY what is going on in their country already because they show it all on their tv shows, and you can fill in the blanks by applying reverse logic to CNN broadcasts! Plus they have more tanks, guns, lasers, nanotechnology (!), computers, soldiers, weapons of mass destruction, internets, ships, planes, IHOPs and paranoia than us. We wouldn't stand a chance in a war against them, so why would we spy on them? I remember when i was a kid, there was a bully who could & would kick my ass. Would i gossip about him, or try to be sneaky around him? No! Why would i bother, if he could kick my ass anytime he wanted to? My plan was to not give him any reason to be angry at me. If he'd heard i was actually spying on him or gossiping, he'd have been ticked. Same goes here. If the Americans wanted Canada, they would pretty much just take it. Of course they'd never be able to deal with our winters (or rather lack of spring) and the lack of IHOPs would send them screaming south. Plus our beer would get them too drunk, just like that episode of Star Trek where Scotty drinks the bad Aliens under the table. Scotty, or rather James Doohan, by the way, was Canadian.

Fourth, why the hell would anyone want to track the whereabouts of American contractors of any kind? They're either in Canada, or they're in the States. And so what if they're in Canada? What would the so called Canadian Spy Club (CSC, not to be confused with the CBC [Canadian Bi Club]) do even if they could track the whereabouts of these American dudes? Here's how the conversation might have gone...
Canadians: "Well sir, we've tracked the whereabouts of these American Contractors to Moosejaw. We're not sure what kind of mischief they're getting up to, eh, but we think they're headed for the trolley car or Mayor Dale McBain's house".
Fifth, i can't really expect the average American to know what the Poppy is supposed to symbolize here in Canada - we can't really expect them to recognize it as anything. Expecting them to know anything about our symbolism & history would be like expecting us Canadians to know about George Washington and the cherry tree, the Mason-Dixon line, Pearl Harbour, and that flag planting thing at Iwo Jima.
And really, every good Canadian knows that we infiltrated America years ago, with operation "our comedians, actors and musicians our better than yours and we're sending them your way".
Except Nickleback. No one knows what happened there. You can have them.
(BTW - most of my relatives are exempt from this little rant. Most of them actually know a thing or two about their neighbors to the north.)
