We're back

We're back.

A special thanks to Air France, first for losing our infant car seat on the initial leg of our trip; then, for returning home to Boston about 5 hours after scheduled, minus both of our pieces of luggage. Hopefully they will show up sometime today.

And a real thank you to our two kids who actually behaved themselves reasonably well on the flight back.
