Stretch Divs to Bottom of Page - 960gs

HTML & CSS
1

I’ve almost finished one of my first sites using 960gs, but I’m struggling to find a way to get the bottom boxes in each column to stretch down to the footer so that the bottoms all line up.

Here is the page: http://msg.staging-site.eu/sea-kayaking/loch-hourn-and-knoydart-fjord-expedition/

And this is what I am trying to do:

The content of each box comes from a CMS, so I cannot give the boxes fixed heights.

Even if I can somehow give the illusion that the boxes line up, that would be great. Any ideas?
