>> this race to discover the earth's past is a very exciting one and people want a piece of it. >> sue had back a living entity to me after all our work in the field and what we were finding out about her life. and i really missed her when she was gone. so one way that i was able to sort of help that was to go and visit her and to talk with her through the window, looking at the container, so i could see her, see that that container was still there. not moved to some other place in timbuktu or something. and just kind of had some little conversations with her.
