Off topic, I know, but the joke about the gates making a "BZZZZZTT" sound every time you go through reminded me of an image from using the automated gates in DC.
Anyone see the movie "Gattaca" with Uma Thurman and Ethan Hawk? My friends and I made fun of the "Valid" response they would hear each time they entered the space agency doors and get the little DNA check on the turnstile.
I've always just thought it would be a funny real-life idea to have some little device confirming your "validity" each day. So that's my vote for the gate response when using the OTTER card
: "VALID"
