Ja, Ive planned a loose route from BA down south to the glaciers and then up the west coast to panama, still have to plan for central America, the route took a while to plan, but its pretty decent, with lots of riding through national parks and wilderness. Its similar to what most of the guys have been doing that Ive talked to. I reckon you just need to know what places you want to go through and what highlights you want to see, in-between is adventure. We plan on camping the majority of the way, which lands up very cheap in remote areas.
About the bike issue- I'm going to ship mine across, with all the extra equipment and mods. Having to go through all of the bureaucracy and stuff with foreign currency in a foreign language just seems like too much of a headache. There's two of us going, so that halves the price of shipping at least, when we have a date I'm just going to post it on the forum on the off chance that someone wants to share a container.
