"The most comprehensive exhibit ever presented on the ancient middle eastern city of Petra comes to Grand Rapids, Michigan for the third and final leg of its U.S. journey, featuring over 200 exceptional objects "
Well, I guess I won't get to see it this year.
If the Middle East calms down a bit the next few years, maybe I'll take a trip and see it for real. I have seen some interesting TV specials on it, and here is a site proclaiming itself to be "The Complete Petra" site:

The author of that site annoys me (not by going out of his way, or because he knows me, 'cause he doesn't). A pretty good source for links though.
