I'm planning to ride from Seattle to Argentina on my XR650L with my friend on his KLR650. Departure date of October 1st 2013. We are wondering what paperwork we need for each country including visas and mandatory insurances. Does anyone know of a good resource to find this information? We don't want to get half way and find out we didn't apply for some piece of paper and cant cross a boarder. Or get pulled over and taken to jail for not having the right insurance or whatever other paperwork. Thanks for any comments!
