I'm finding there are more and more fairly irreplaceable things which OTHER people are depending on me to have in Paris (the Brussels train tickets, the Sorbonne pre-registration certificates, etc.) and which I can't put in my checked luggage just in case it is lost. Normally I'm pretty cavalier about stuff getting lost, plus the non-replaceable essentials for just me would be much less bulky (passport, money, ticket, journal). Alas.
Anyway this is a good time for my favorite buzzard joke...
So this buzzard is going to take a plane to New York and on the way to the airport he sees some roadkill. Feeling a bit peckish, he grabs it to snack on.
He still has it at the gate, figuring he might as well save it, everyone knows you never get enough to eat on those things.
At the plane door the flight attendant stops him, "Sir, you can't bring that on the plane."
The buzzard replies, matter-of-factly, "Why not? It's just my carrion."
