Ok, so I finally did it.... I decided on a new number......8
Really I didn't have many reasons. It was the only single digit car number that was symetrical (I like that) that wasen't already taken in our series. Being a single digit it's cheaper to get decals, stencils, etc. for my car in the future (yes, I am that cheap sometimes). No personal significance for me. Couldn't find a good number that did have some sort of significance.
and
I recently watched one of my favorite movies "The Postman" with Kevin Costner. In it the Holness is the army tring to take over the owrld and they live by "the rules of 8" and my wife hates that. So I picked 8 to get under her skin!!
Anyway thanks for all your help!!
