Find a traveller from this forum who wants to sell a foreign registered bike. Go to a Notario in Uruguay, (I know of one I used - $10), with the relevant paperwork, make a "Carta Poder", and from personal experience, this will do for at least 11 countries in Latin America. When you are finished, find a traveller who wants to buy, and do the same thing, not necessarily in Uruguay - I did the same in Guatemala. Argentina is a pain, so don't consider, but Montevideo is a pleasant trip by boat and bus via Colonia.

How much does a man live, after all?
Does he live a thousand days, or one only?
For a week, or several centuries?
How long does a man spend dying?
