I've never seen any women directing traffic, or in security, and my hubby occasionally did security at the DC (he loved it, was usually in an area where he couldn't hear a thing, lucky bastard!).
And those "brothers" that direct traffic, just one big joke! They usually just stood there waving their arms, not really knowing what to do and ended up making things more congested than they should be.
If there is the shortage of "qualified brothers" that I hear there is, this is acutally good news. One more brick taken out of the wall, pretty soon it will start to crumble.
