Navyg8tor is a combination of a few different things:
First, I am in the Canadian Navy;
Second, I drive a Lincoln Navigator;
Third, it is a reference to the use of navigational equipment used in the game;
Lastly, the 8 is just to make it look a little different and to help it stick in the head.
When I first signed up on the site I had my first name as my handle and it was kind of boring, so I though this one up, then started a new account with it when I had my first find.
