Upon my return to Boston on February 9th (delayed a day due to weather), I started the hunt for my passport in earnest.
The last time I'd definitely had my passport was January 11th when I cleared through security at Reagan National Airport after the LSA conference.
I contacted Reagan National, Logan, JetBlue. Nothing.
I contacted my dry cleaner and car rental place. Any friend whose car I'd been in. Nothing.
I went to the RMV (where I'd recently renewed my car registration). They had a whole drawer full of passports left behind but not mine.
For the next few days, my wife and I turned our apartment upside down looking for the passport.
