Kept meaning to post this. There's a trio from my hometown that recently took off on a sailing trip around the world. Yes, really! You can follow their adventures at The Captain's (B)Log.
It is a couple, and half of another couple (the other wife is not willing to leave the grandkids!). They are currently around Toronto, and expect to sail West around the world. The wife & other members of the families will meet them at various spots around the world. How cool is that? Dream of a lifetime. But we can all go along with them, so to speak.
