I went for all out obscurity on mine. Only the geekiest of computer geeks would ever get it.
License tag is 100 001. In 6-bit binary it equates to 33. On the ASCII table, 33 is the !
So I'm driving around with the binary expression for an exclamation point.
Most people think it's a reference to racing, like 100 wins, 001 loss. People have also asked if it's a government car, as some of them have oddly numbered tags.
I don't really care if anyone 'gets it' or not. I like it
A friend of mine in NC got a license tag that says G8RSSKDK (Gators **** d!ck); he went to FSU. How that ever got past the NC DMV review board is beyond me.
