Hola, I see you are traveling in South America. If you are intending to ride into Argentina they have made a change starting JAn 6th, 2013. We must pay a reciprical tax of $160 USD online before entering, I got turned back at the border for not having mine..... fortunately it was into Chile where the cafe had fast WIFI and a Printer!! To save you lots of hassle. Here is the link to the info page. https://virtual.provinciapagos.com.ar/ArgentineTaxes/ComoFunciona.aspx But under the log in you need to "sign In"to get the "entry Code" or go to this link to fill in your info and get entry code then sign in and pay online. Print out payment receipt and take to border with you. https://virtual.provinciapagos.com.ar/ArgentineTaxes/Registro.aspx Pass along to all riders!! Ride safe. Mark AKA Radioman PS: pass along to any other US, Canadian, or Australian riders..... or they will be turned back at border. Cannot pay at Border!
