How to do it? Probably almost as many possible answers as there are travelers. My approach may not work for others, or they may find it distasteful:
- Pay off all debts including late wife's medical bills.
- Get rid of TV and car; learn to bicycle or walk everywhere. (Bus/train/car rental/plane only when time is a problem.)
- Get medical care from the U.S. Veteran's Administration instead of expensive insurance.
- When children are on their own, retire, sell the house, and hit the road.
- Avoid hotels and expensive cities.
- Stay long enough in one place to rent a room or a tiny apartment instead of by-the-night costs.
This allowed me to relocate eleven times, plus six two-to-ten-day visits to other places. Spent about US$ 31,000 (including gifts/meals for other people) so far—603 days.
