Burt Lancaster wore one in 'Valdez is Coming' dont know what they are called or where to get one from. Great film though.
if you google "campaign hat" you should get that hat.
our forest and park service people wear them. the us 7th cavalry still does for ceremonial events.
our state police are called smokies because smokey the bear wore one when he warrned us about forest fires and they do when they are giving us speeding tickets.
as good as the movie was read the book. who'd a thought elmore leonard wrote some best old west fiction ever.
