I went to Chile & Patagonia a few years ago. I'm sure you got your route pretty much set, but if you don't here is a couple of off the beaten path gems I found
1) is Los Arrayanes National Park in the lakes district in Argentina. features the red bark arrayanes trees
2) is the chilean island of Chiloe and it's capitol Castro. It's just a quick ferry ride from Puerto Montt. I did an overnight there because I had an extra day to fill. i wish I could given it a couple of more days. The town of Castro is famous for Palafitos, small houses on stilts at the waters edge.
I've also thought about moving to Nevada after I retire for tax reasons. But right now I'm happy here. Several years ago I traded my SF Bay Area equity in for a small house at the beach close to Pismo. I'm lucky now that I'm established here in Central Cal, it will be hard to move.
