Some of you seem to be suggesting stories about migrants and whatnot because they'll be easier to make links, you have to realise that although it might be easier but your marks probably won't be as good. The texts I used last year were the song "I was only 19" by Redgum and the movie Stand by Me. Songs are good because they're easy to remember quotes from (thats not just for phys. journeys - but anything). Also have a look Andrew Denton's Enough Rope site, there's some good interviews there with people who have been on physical journeys (I think his name is Aron Ralston?: the guy who had to chop his arm off to survive). Another good idea is to look at backpacker/travel websites, there are some good articles in places like that about physical journeys. And photographs and cartoons are usually fairly good and easy enough to find.
I found it easy enough to create links between the poems and most texts, if you find a good physical journey (say text that you actually enjoy), you should find it easy enough to describe and connect to the poems...
Hope I've been of some help.
