Hi,
my parents are starting to get the travel bug, and would like to see more of the world (health permitting) and they have been interested in volunteering abroad for portions of time. They are getting up there... 54 and 61 years old I think, but have accumulated a lifetime of work skills. The long Saskatchewan (Canada) winters are starting to get to them, and I have been pushing them to volunteer abroad. I know that there are various places where you can get room and board in exchange for labour, but what about flights and whatnot?
Ideally, I could see them in Central/South America - but they may be open to any locales around the world. Can anyone help me out with links or info with regards to this?

Thanks!
