I was riding close to my home when I noticed the motorcycle in front of me, a Triumph Tiger 991, had a Brazilian flag on the top case. I spoke to the rider when he stopped off at the next gas station. He and his two friends on an older Honda Shadow, were indeed riding from Brazil to Alaska. They left Brazil 3 months ago. They transported their bikes from Columbia to Panama to bypass the most dangerous section. They said it cost $1100 to transport their motorcycle over that section.
They plan to go to Anchorage and then to Montreal. After that, they will load up the bikes on a ship and go home. That's an epic trip!
For my part, I took them out to dinner and welcomed them into my home for the evening.
I hope someday I can accept their offer and ride to Brazil to visit them
