I spent some time on oplates.com before finally picking a plate that has absolutely nothing to do with Crossfires. I threw away my list of suggested plates, but the one that I remember (that was available) was "2 CEDAR". I also think that BENZ ISH was available (although my wife thought that one was REALLY stupid).

Have fun with your search. The Oplates.com website is a great resource.

Don't forget that the letter Q looks an awful lot like the letter O and can often be used if the specific plate combination has already been taken.
