Great idea for a book I have done the overland track 4 times now and was just thinking about the people I have meet.
doctors ,vets ,defence force ,pilots ,train drivers,trades of all types and a mirade of other diverse jobs
Meet heaps of other cultures and am surprised how you can still communicate without knowing the other language.
Be a great book just sitting say at pelion for 3 weeks and writing about the people and stories you meet.
Thats a book I would read.
