ie column css problem

On this page: http://www.asburypark.com/wordpress/?page_id=10 I have a css column problem in IE for windows. I develop on macs and the page renders fine in Safari, FF and IE for mac, but the 3 columns appear stacked in IE for windows instead of side by side. Can anyone see the obvious (but not to me) CSS problem that I have? This is one of those things where I sure the solution is staring me right in the face.
