This is sort of like the Da Vinci Code but set in the US. You're going through the various famous sites looking for a buried treasure. What mistakes are in this movie?

First, I love the northern areas of our globe, so I was intrigued by the Arctic Circle scene. Unfortunately, they got it all wrong! During the summer it's light pretty much 24 hours a day and gets up to 80 degrees. There wouldn't be snow!!

Being a genealogist, here's one that really got to me. The Declaration of Independence is a very old document, stored in helium to keep it intact. If they just grabbed it and kept rolling and unrolling it, it would have fallen into pieces.

Not only that, but they stick lemon juice on it to show the invisible ink. Really, though, lemon juice IS an invisible ink. Most kids play with this to send messages at least once. If they put this all over the back of the document and heated it, the whole back would turn brown as a result.

Here's one that makes no sense. They claim in the riddle that 55 men signed the Declaration of Independence. It was 56! Surely that is a very basic number to get right, considering how important the document is to the story ...

Another error that really bugged me each time I saw the movie involved the clocks. First, the clock on that bill is 4:10, not 2:22, so it's wrong to begin with. Next, the sun obviously moves in the sky in different paths based on time of year, so you can't just say 2:22 on ANY day would match up properly. Third, they didn't have world-wide standardized time back then! They determined noon by when the sun was directly overhead AT THAT SPOT and then made other times sync up to that. So noon in Washington DC was different (by a few minutes) from noon in Boston MA.

If you've got other errors to share, please post them in our forums!
