I too am considering something like this. I retire Dec 30th this year. Want to spend a few years visiting family around the country and seeing some national parks and generally exploring the US via bike.
Then perhaps move to someplace where you can live on the cheap. MSN had a "10 top places to retire" article the other day. Ecuador came out #1. On the equator and good riding weather year round. Said a person could live very well for 17k a year.
