...currently in Potosi, and planning on going to Uyuni, the Salar, Parque Avaroa, and into Chile, staying the night at San Pedro de Atacama before heading into Argentina via Pasa de Jama. I have a Bolivian bike that I bought off a couple on Colombia. The paperwork matches and I have a bill of sale and no problems yet at borders. The plate fell off but I have documentation that the bike is legit, and written and stamped permission from the police in La Paz to ride the bike. Does anyone have any experience doing this crossing? Do I need to take care of things on the Bolivian side at Uyuni? Any heads up on what to expect (fees, problems, etc.) would be appreciated. I'll only be in Chile a short while before I head over the Pasa de Jama and into Argentina, stopping in Salta. I have to be in Mendoza around the 17th. Im a U.S. citizen, so I imagine that I have to pay for a visa online, print it out, and all that. Can anyone with experience doing this tell me how easy/hard it is, and if there is any wait time? I usually play things by ear but it seems pretty remote where Im going and Im a little pressed for time so I want to make things as easy as possible on myself. Thanks for any help and advice.
