I'm a retired computer-geek Aerospace engineer. My wife is a retired librarian (forced out of work by back problems). We live in Southern California, and most of our traveling is car trips to places we can comfortably drive to for a 2 to 4 week road trip. But that said, this year we spent a week in NJ (for a family reunion) and NYC (just playing tourist), and next year we're planning a trip to Israel for a genealogy convention (my wife's passion).
We're attracted to the B&B thing because we've discovered that we really do prefer the comfort and convenience of having a real, functional space to call home-away-from-home.
