When I am trying to fall asleep I like the picture various retirement scenarios in my head. One of them is a little condo on the beach. I could walk the beach every morning with a metal detector and looks for doubloons.
Another thought is to spend a year traveling the country in a small RV. If it wasn't huge I think I could handle a little house on wheels. We could go from state park to state park and just camp out and see the entire USA. Just like the Albert Brooks movie except perhaps without the messed up parts.
It's doable - you can pick up a small to medium sized RV and get an rv insurance quote, plan some reservations and go.
