An Inconvenient Truth: free

I have just learnt from Emma that Intrepid Travel want you to see Al Gore's An Inconvenient Truth. They really want you to see it. So much so, that if you send them your ticket stub (and your family's, friends' and colleagues'), they'll reimburse you.

That's awesome.

(oh, and if you haven't - totally go see it. it'll change the way you see the world)
