Excellent stuff lads and ladies. Thanks so much for all your answers, keep any more advice coming. I'll have a look at all the links. JK2, I can't afford to do that organised trip unfortunately but everyhthing else you've given is gold! Looks like I'll prob do the train to Lake Titicaca and La Paz then head down from there to BA in one go if I have to. Will have a look at it all. Cheers for all the info and keep it all coming if you find anything more!!
