Sorry for hijacking your family-friendly post! :-*>
I don't set out to be contentious, it just sort of happens naturally sometimes! (I love to debate about environmental issues)
As a bit of a tangent picking up on what you were saying about travel by wind and boat, I actually have a bit of a dream of learning how to sail and traversing the Atlantic in a yacht as crew, as I would like to make a habit of visiting Brazil every couple of years and I'm not comfortable with the air miles. It's a very doable dream I think!
Feel free to comment and debate on any of my posts! Cheers
