Your doing a great job documenting your travels. I'm learning a lot for future trips.
Thats just it, there are many neat places in the world that one can live very well and cheap. I have a friend in Thailand that lives like a king on $2000 US per month. Cost of living is 25-30% of the US. Just have to be creative and willing to take a small risk. And it does'nt have to be forever.
I'll be curious to see what you think of Costa Rica for expat living. Take care!
