Well, certain kinds of ID. Right after 9/11, I started my own little research project, and can tell you that it's more like
most government issue photo IDs: I've found that the good people at SFO will absolutely wig out when presented with an out-of-state Conceled Carry of Firearms permit, and nobody seems to like the Library of Congress Reader Identification Card

.
Both are government issued photo ID, mind you.
