There was a promotion for "Sgt. Preston of the Yukon" that was hatched during the 1950's...if you sent in the box tops, you got a deed to one square inch of a land plot int he Yukon Province of Canada. I've heard that people show up at the Antiques Roadshow with the deeds and want to know if they're still of any value...sadly, they aren't...I've seen the paper deeds for sale on Ebay. Not a scam, just a promotion for a TV show and a breakfast cereal but fun to remember. So what's the harm? And if it helps to keep some land from being developed, all the better...I can think of a few places in the USA where it might be a good idea for a lot of people to buy a square foot or a square inch or an acre just to keep the land from developers who want to create more suburban sprawl. Seems like it's all in good fun...but if you do want to put a house on it, try this guy's products:
