+1 Another way to think about it is, putting the first 4 numbers up against a mirror and seeing their position backwards.
I was going for this when saltysam said putting the first 4 numbers up against a mirror and seeing their position backwards. I'll go with this then: 39633963 Thanks! ! !
We still don't have a winner, so I'm going to make it real easy. The serial number is a repeater and everyone can guess again. I'll check on Sunday night at 10pm Central Time, and if we don't have a winner then, everyones' post number will go into a hat and I will draw a winner. As always, good luck! So by guessing another time, you will have two entry's in the drawing; provided the posts are an actual guess. For new players, it will just be one. (IF its needed at all)
