Scientists often forget to carry their credentials with them. Investigator Earle Spamer, of Philadelphia, sends this first-hand account, which shows the value of carrying proper credentials:
On a recent visit to the airport, I was asked to show identification. Upon producing a photographic driver’s license and my official Improbable Research Investigator card, I was immediately set upon by anxious hooligans in the execution of their official duties. I protest. I am an official, card-carrying Investigator. Also, I believe that my beard gives me a respectable (and admirable) profile. To add insult to injury, they would not validate my parking stub.
