For me, it's not so much get out of the way, as it is to look up and observe it directly. On its penultimate orbit it should be observable all along its orbit and when it does de-orbit there is probably a 2500 mile wide swatch where you will get to see some portion of its disintegration. These were pictures of Mir : http://news.bbc.co.uk/2/hi/asia-pacific/1238009.stm for example.
