Chas, just buy an old sailboat and you can live pretty much anywhere you wish. Of course, there needs to be water if you want to change locations once in a while. There's a neat thread on one of the sailing forums titled "Voyaging on $500 a month." Believe it or not, there are an awful lot of couples and families doing this, and within that $500 a month budget. No ghettos for them - many live in tropical paradises. I met a lot of them in the Florida Keys - really fun people to be around.

Cheers,

Gary
