DEADLY TREASURE HUNT

This is a Fiction book about, some Guys in Vegas that were bored and wanted something new to bet on, so they created a treasure hunt. The treasure hunt rules are, it is to be held in a two hundred mile radius, there is no contacting the players, the clues cannot be buried, left they way they were found, and no working with the other teams. The clues are in machines that are shaped as question marks, and the markers with the payouts are the shape of monuments and take five keys to open.
Now I have woven in a bunch of jokes so it can be a bit blue, I put a small boy into it for little Johnny jokes, a blonde, a Priest. etc. Some of the players get hurt and replaced, like breaking a leg, mauled by a tiger, stuff like that, but keep the main players.
Now this game is set when a Vegas show girl throws a dart at a map of the U.S.A. a town in the middle of Wisconsin, so it goes into the Upper Peninsula of Michigan, into Minnesota and Illinois. It is amazing how many cool places there are, Museums, Churches, Parks, Caves, Circus, a Pyramid, even the Mall.
Is there a love story, well maybe a couple, there is two couples that leave the game together, oh ya its always nice to have a spy in the book, well a ex-spy.
