Been doing this for years -- in the US (Score 1)

Generally your cost of living depends on the desirability of your location and your standard of living which can vary anywhere. Note all the folks living in NYC on minimum wage. I've been working about 15 hours/week for years and live quite well in the US while accumulating savings. Being fortunate to bill out at a high rate (in my case, about $100/hr) makes a BIG difference. Still, if you get rid of all the big line items in most folks budgets: rent/mortgage, phone, cable, loans, eating out frequently, etc., you can bring your cost of living way down. If you're saddled with debt...not so easy. Right now, cost of living is about $2-3K/mo. for 2 people and a dog, living on the waterfront and traveling constantly. Home is a sailboat. Of course, we could live much cheaper, but we eat and drink very well and have a nice boat that is kept well. The whole East Coast is home. Could do this even cheaper with a small camper, or super inexpensive with a bike with paniers + tent. I have a friend who biked over the whole of the Americas (yes, ALL of them) for 2.5 years living on about $7/day. Naturally, she didn't have to work very often or for long.
