inviting place for americans who just wanted to get off the grid, own rules. you'll remember travis mcgee, the mystery solving boat bum who lived on a houseboat in miami. the busted flush. people used to live like that. less and less today. >> travis: when my wife passed away a few years ago, i was living in a condo and didn't want to do that anymore. now i'm on this piece of iron. >> anthony: bob, aka captain bob, is still here and still living on his boat in the miami river. >> bob: we sit out here and we look like we're enjoying ourselves, but it is really hard work. just sitting here looking pretty, it's not for everybody. but yeah, it's a good life. >> anthony: i've had many friends over the years who live on boats, work on boats, but these were just degenerate wind addicts. this is more of a lifestyle choice for you. >> bob: it is. it's got a machine shop on board.
