The one in the pic looks just like Maine's version.
My mother just got a new one (New Hampshire) - it's the same width, and a little thicker... but half the height! Much better for bike mounting.
Rich, my place of employment just installed a new automatic security gate, which opens using some sort of RFID card, I think; you wave it in front of a panel and the gate opens. The card just fits into the little "key storage" pocket on the sleeve of my riding jacket (sleeve pocket and gate panel both on the left, thankfully). Just ride up, swipe my left hand across the panel, and open sesame!
Do you ever offer any particular hand gestures while you're waving through the toll? I can think of any number to choose from...
