Would you rather have a six sided star of David? I've done the firefighter, police, postal worker thing, there were a lot of other people that were lost, that don't fit into any specific category. I was memorializing the event. Did you read the text? What about the restuarant, waiters, waitresses, clerks, typists, etc. that were lost--maybe you have a suggestion how to reflect their memories...there were also messangers, janitors, all the little people...not just firefighters, police and postal workers. Are you just into stereotypes?
