The five regions include British Columbia, prairies, Ontario, Quebec, and maritimes. Well, not exactly. An alternative approach is to have a mountain region including B.C. and the mountainous part of Alberta. We might quietly move the goal posts.

An advantage of this book is it would get Canadians to explore their own country. The territories are explicitly out. Too many problems. Nova Scotia is where the mysterious Oak Island treasure is.

There is nothing wrong with having multiple treasures in the same zone. It is assumed that treasure hunts won't be overt about the region, but there's no rule against this.
 
 
 
 

How big is the book? A coffee table book? I prefer smallish. I hope there's enough material to fill a book. I hope somebody writes a big story.

For the cover of the book - and spine - treasure should hit the eye for this book called Thesaurus. The cover could have a map of the country, multiple classic treasure chests. Something natural, trees. You can't lose with Lake Louise. Ten provincial coat of arms. I like a helicopter shot of a snowy neighbourhood, kind of cookie cutter. It's probably the publisher's decision anyway.

Canada has snow, and seasons. When should a book be published?
 
 
 
 
 
 
 
 

A treasure hunt should not be too easy because it would get solved right away, players would no longer have a challenge, and books would not be bought. A treasure hunt should not be too hard because players would be frustrated and put off, urban areas get redeveloped over time, and designers die. That's an advantage to having a variety of treasure hunts.
