Spidey,
I can honestly tell you that the OKC Memorial was the most tastefully done memorial that I have ever seen......and I live here in the Wash DC area. It will literally send chills up and down your spine. And, if you go there....get the commemorative coin that they offer...great thing to pass on to your following generations.
Sorry I can't help you on up-to-date info on OKC....(born and raised in Enid, OK..left there in '74). I'll be going to OKC myself in October.
