When I was in Deadhorse Alaska (near Prudhoe Bay) ran into a couple of argentinians who had driven up. About as far north as one can drive... and they went south to patagonia to start their trip, too.

Always wanted to do that.

Great thing about traveling in alaska-- you can just pull over to the side of the road and sleep. Spent weeks doing that, and the only "incident" was when an Alaskan Pipeline worker woke me up (it was noon! I my clock was thrown off by the 24 hour sunlight) to make sure I was ok. (I was relatively near the pipeline at that point, and they patrol it.)

Thanks for sharing your experience, I'm enjoying reading it!

I remember seeing a lot of Canadian plates while I was hitchhiking down to Ushuaia on the other end. I think that route has a siren call to a certain type of person. Some of them looked very relieved at that final border crossing :)

Yep, I drove up to Deadhorse, and then down past Ushuaia until the sign at the end of the road.

Sleeping on the side of the road like that is not only in Alaska, I camped almost my entire trip.
