My next trip

Premature? Perhaps. But this happened on my last trip too. I started planning my next trip while I was still in the middle of my current trip. And after talking to other travelers I've found others do the same thing. I'm still really, really excited about my current trip and don't want it to end (in fact I'm not even thinking about 'the end' yet). But I know it will end at some point in the future, and I guess I need something to look forward to in the long term. So about a week ago I came up with an idea for my next trip. I wanted to write it down so I don't forget about, or neglect it.

I really like these 'overland' trips and have been traveling via ground transportation whenever possible for my entire trip (aside from 2 notable exceptions that I couldn't get around). In fact I really go out of my way (and sometimes at great cost) to stay on the ground. I've been planning on going to South America for my next trip but I was thinking I would have to fly down to Chile. But now I have come up with a better idea. Traveling overland from Seattle (or maybe even Alaska) down through Central America (including possibly Baja, Mexico first) and all the way down the western coast of South America to the southern tip of Patagonia in Chile. That is as much 'planning' as I have down right now, and I'll save any further planning until much later. But it gives me something 'adventurous' to think about as I feel there is not much 'adventure' left in the southeast asian backpacking circuit. I'm definitely going to learn some Spanish before I tackle this trip though....
